In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference."}],"publication":"Photonics","issue":"2","doi":"10.3390/photonics13020128","language":[{"iso":"eng"}],"article_number":"128","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/2304-6732/13/2/128"}],"article_type":"original","intvolume":"        13","publication_status":"published","date_updated":"2026-02-02T21:38:34Z","author":[{"first_name":"Dominik","last_name":"Metzner","full_name":"Metzner, Dominik"},{"first_name":"Jens","last_name":"Potthoff","full_name":"Potthoff, Jens"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf","id":"30525"},{"first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","full_name":"Förstner, Jens","id":"158"}],"publication_identifier":{"issn":["2304-6732"]},"year":"2026","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","oa":"1","quality_controlled":"1","citation":{"ama":"Metzner D, Potthoff J, Zentgraf T, Förstner J.

In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots."}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/abs/10.1021/acsomega.5c09476","open_access":"1"}],"article_number":"14448","doi":"10.1021/acsomega.5c09476","publication_identifier":{"issn":["2470-1343","2470-1343"]},"author":[{"first_name":"Naresh","last_name":"Killi","full_name":"Killi, Naresh"},{"last_name":"Kumar","first_name":"Amit","full_name":"Kumar, Amit"},{"full_name":"Nebhani, Leena","first_name":"Leena","last_name":"Nebhani"},{"last_name":"Obst","first_name":"Franziska","full_name":"Obst, Franziska"},{"full_name":"Richter, Andreas","first_name":"Andreas","last_name":"Richter"},{"last_name":"Reineke Matsudo","first_name":"Bernhard","full_name":"Reineke Matsudo, Bernhard"},{"full_name":"Zentgraf, Thomas","first_name":"Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","id":"30525"},{"id":"287","first_name":"Dirk","last_name":"Kuckling","full_name":"Kuckling, Dirk"}],"title":"Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction","year":"2026","intvolume":"        11","article_type":"original","date_updated":"2026-03-10T08:27:15Z","publication_status":"published"},{"date_updated":"2026-03-10T08:32:37Z","publication_status":"published","intvolume":"        38","article_type":"original","year":"2026","title":"Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation","author":[{"full_name":"Jin, Xiao","last_name":"Jin","first_name":"Xiao"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","id":"30525"}],"publication_identifier":{"issn":["0935-9648","1521-4095"]},"doi":"10.1002/adma.202511823","main_file_link":[{"url":"https://advanced.onlinelibrary.wiley.com/doi/10.1002/adma.202511823","open_access":"1"}],"article_number":"e11823","language":[{"iso":"eng"}],"abstract":[{"text":"Abstract</jats:title><jats:p>Metasurface holography offers a powerful approach for manipulating wavefronts at the nano and micro scale. Extensive research has been conducted to enhance the multiplexing capacity for diverse wavefronts. However, the independence of multiplexed channels is fundamentally restricted in techniques using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing concept is presented based on non‐injective transformation. By employing joint optimization on two metasurfaces, different channels can be independently designed without any constraints on the output wavefronts. To validate this approach, ultra‐compact orbital angular momentum (OAM) sorters are designed. In these experiments, the output beams from different channels can be independently mapped to 2D positions with high fineness. In another application of wavefront‐multiplexed holography, 10‐channel multiplexing is experimentally achieved with minimal crosstalk and without the need for post‐processing. These results demonstrate the independence between channels enabled by the non‐injective transformation in the method. The precise wavefront control and high multiplexing capacity underscore its potential for scalable wavefront manipulation devices.","lang":"eng"}],"publication":"Advanced Materials","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"date_created":"2025-10-06T05:42:21Z","status":"public","user_id":"30525","volume":38,"_id":"61523","publisher":"Wiley","quality_controlled":"1","project":[{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142; TP A08: Nichtlineare Kopplung von Zwischenschicht-Exzitonen in van der Waals-Heterostrukturen an plasmonische und dielektrische Nanokavitäten","_id":"65"},{"name":"TRR 142; TP B09: Effiziente Erzeugung mit maßgeschneiderter optischer Phaselage der zweiten Harmonischen mittels Quasi-gebundener Zustände in GaAs Metaoberflächen","_id":"170"}],"citation":{"mla":"Jin, Xiao, and Thomas Zentgraf. “Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation.” <i>Advanced Materials</i>, vol. 38, e11823, Wiley, 2026, doi:<a href=\"https://doi.org/10.1002/adma.202511823\">10.1002/adma.202511823</a>.","bibtex":"@article{Jin_Zentgraf_2026, title={Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation}, volume={38}, DOI={<a href=\"https://doi.org/10.1002/adma.202511823\">10.1002/adma.202511823</a>}, number={e11823}, journal={Advanced Materials}, publisher={Wiley}, author={Jin, Xiao and Zentgraf, Thomas}, year={2026} }","ama":"Jin X, Zentgraf T.

However, optical networks constructed from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues, as the number of required beamsplitters scales quadratically with the number of optical modes for a fully connected network. Metasurfaces offer a promising route to\r\novercome these constraints. By manipulating light at the wavelength scale, compact optical components with advanced functionalities can be constructed, which address several modes simultaneously. In this work, we design and experimentally utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a multimode interferometer composed of two cascaded metasurfaces. We characterize the individual and cascaded metasurfaces by using classical light, showing controllable splitting ratios through tunable phase relations. We then expand the approach to quantum light, employing single photons to demonstrate second- and third-order photon correlations as well as single photon interference across multiple spatial paths. These results establish metasurface-based multiport beamsplitters as a scalable and reconfigurable platform bridging classical and quantum photonics.

In most metasurfaces, near-field couplings are treated as being unfavorable perturbations. Here, we experimentally investigate a structure consisting of sinusoidally modulated silicon waveguides where near-field coupling of local resonances leads to negative coupling, i.e., a negative coupling constant. This gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular polarizations. In particular, fully circular polarization states are not only present at a single point in momentum space (k-space) but also along a line. This circular polarization line, as well as a linear polarization line, emanates from a polarization degeneracy at the Dirac point. We experimentally validate the existence of these eigenstates and demonstrate the energy-, polarization-, and wave vector dependence of this metasurface as well as its sensitivity to fabrication tolerances. By tuning the incident k-vector, certain polarization-energy eigenstates are strongly reflected, allowing for uses in angle-tunable polarization filters and light sources."}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/10.1021/acsphotonics.5c02865"}],"doi":"10.1021/acsphotonics.5c02865","author":[{"full_name":"Wetter, Helene","last_name":"Wetter","first_name":"Helene"},{"id":"69187","full_name":"Wingenbach, Jan","first_name":"Jan","last_name":"Wingenbach"},{"first_name":"Falk","last_name":"Rehberg","full_name":"Rehberg, Falk"},{"full_name":"Gao, Wenlong","last_name":"Gao","first_name":"Wenlong"},{"full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271"},{"id":"30525","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","full_name":"Zentgraf, Thomas"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"year":"2026","title":"Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling","intvolume":"        13","date_updated":"2026-04-20T05:09:57Z","publication_status":"published","external_id":{"arxiv":["2512.14452"]},"citation":{"chicago":"Wetter, Helene, Jan Wingenbach, Falk Rehberg, Wenlong Gao, Stefan Schumacher, and Thomas Zentgraf. “Polarization- and Wave-Vector Selective Optical Metasurface with Near-Field Coupling.” <i>ACS Photonics</i> 13 (2026): 2128–33. <a href=\"https://doi.org/10.1021/acsphotonics.5c02865\">https://doi.org/10.1021/acsphotonics.5c02865</a>.","short":"H.

We introduce a paradigm shift using a many‐body plasmonic architecture inspired by statistical mechanics. By moving toward the continuum limit, local geometric variations are statistically averaged out, effectively decoupling optical performance from microscopic disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step dewetting strategy, creating wafer‐scale nanoclusters. This process strategically forms a robust many‐body system by introducing numerous small satellite nanoparticles between larger particles. Crucially, this design achieves a high collective enhancement that surpasses even optimized few‐body systems, despite having larger individual gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility (RSD of ∼10%). This scalable, low‐cost concept establishes a practical route toward reproducible wafer‐scale nanophotonic platforms for sensing, spectroscopy, and quantum technologies."}],"publication":"Laser &amp; Photonics Reviews","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"type":"journal_article","date_created":"2026-07-22T05:49:50Z","article_type":"original","date_updated":"2026-07-22T05:52:38Z","publication_status":"published","publication_identifier":{"issn":["1863-8880","1863-8899"]},"author":[{"full_name":"Kim, Minjun","first_name":"Minjun","last_name":"Kim"},{"first_name":"Vasanthan","last_name":"Devaraj","full_name":"Devaraj, Vasanthan","id":"103814"},{"first_name":"Hyeon‐Seok","last_name":"Seo","full_name":"Seo, Hyeon‐Seok"},{"first_name":"Seong‐Jae","last_name":"Eom","full_name":"Eom, Seong‐Jae"},{"full_name":"Lee, Jeong‐Su","last_name":"Lee","first_name":"Jeong‐Su"},{"first_name":"Donghan","last_name":"Lee","full_name":"Lee, Donghan"},{"full_name":"Jeon, Min Yong","first_name":"Min Yong","last_name":"Jeon"},{"id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf"},{"full_name":"Lee, Jong‐Min","last_name":"Lee","first_name":"Jong‐Min"}],"year":"2026","title":"Engineering Disordered Many‐Particle Plasmonic Nanoclusters for Wafer‐Scale Uniform and Giant Electromagnetic Field Enhancement","doi":"10.1002/lpor.71610","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/10.1002/lpor.71610"}],"article_number":"e71610","quality_controlled":"1","citation":{"apa":"Kim, M., Devaraj, V., Seo, H., Eom, S., Lee, J., Lee, D., Jeon, M.

In gas sensing, optical sensors are often used to detect gases such as CO, NOx, and O2. Oxygen sensors typically incorporate dyes into oxygen-permeable matrices like polymers, silica, or zeolites. Alternatively, semiconductor surface chemistry can enable O2 detection. However, these approaches are often limited by slow response and recovery times and low selectivity, restricting their practical applications. The metal-organic framework MOF-76(Eu) and its yttrium-modified variant, MOF-76(Eu/Y) are reported to exhibit highly reversible and fast optical responses to varying O2 concentrations. Time-resolved emission measurements are performed over short (seconds) and long (hours) timescales using N2 and synthetic air mixtures. Cross-sensitivity to humidity is analyzed. Multichannel scaling photon-counting experiments confirm quenching at the linker level, as the emission lifetime remains nearly constant. Yttrium significantly improves stability and performance at room temperature. Structural and optical changes induced by yttrium are investigated. Additionally, MIL-78(Eu), another Eu-BTC-based MOF with a different coordination environment, is synthesized. Unlike MOF-76(Eu), MIL-78(Eu) exhibits distinct optical properties but lacks a reversible response to O2. These results highlight the potential of MOF-76-based materials for high-performance O2 sensing.","lang":"eng"}]},{"user_id":"30525","publisher":"Wiley","_id":"66632","status":"public","oa":"1","quality_controlled":"1","citation":{"chicago":"Devaraj, Vasanthan, Sunghyun Kwak, Hyeongjip Kim, Sang‐Keun Sung, Jong‐Min Lee, Thomas Zentgraf, and Won‐Geun Kim. “Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies.” <i>Laser &#38;amp; Photonics Reviews</i>, 2026. <a href=\"https://doi.org/10.1002/lpor.71686\">https://doi.org/10.1002/lpor.71686</a>.","short":"V.

Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways. These results provide process‐enabled guidelines for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies."}],"publication":"Laser &amp; Photonics Reviews"},{"has_accepted_license":"1","status":"public","ddc":["530"],"user_id":"158","_id":"66744","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","page":"1-12","project":[{"name":"PhoQC: Photonisches Quantencomputing","_id":"266"}],"citation":{"mla":"Farheen, Henna, et al. “Efficient Silicon Nitride Quantum Interconnect for Intrinsic Silicon Nitride Single-Photon Emitters.” <i>IEEE Journal of Selected Topics in Quantum Electronics</i>, Institute of Electrical and Electronics Engineers (IEEE), 2026, pp. 1–12, doi:<a href=\"https://doi.org/10.1109/jstqe.2026.3722063\">10.1109/jstqe.2026.3722063</a>.","ama":"Farheen H, Chen Y, Chen P, et al.

To that end we consider Gaussian superpositions of semi-guided waves, for a range of in-plane propagation angles, here named “semi-guided Gaussian beams.” This paper collects a series of relations that characterize these wave bundles, with emphasis on their divergence.

However, the realization of multifunctional Janus metasurfaces in the optical band still faces enormous difficulties and challenges, which are essentially limited by the anti-error design and processing methods of multi-layer cascade metasurfaces. Here, a triple-layer Janus metasurface based on cascaded plasmonic nano-antenna arrays fully buried in SiO2 is constructed. Among them, the cascaded plasma nano-antenna consists of two types of enantiomers for each wavelength. Each enantiomer is fabricated with two layers of L-shaped nanostructures with phase modulation and one layer of dimer nanostructures with polarization selection stacked alternately along the optical axis. We experimentally show that the Janus metasurface achieves bidirectional asymmetric multi-channel holographic encryption, simultaneously using propagation direction, phase, polarization, and wavelength for the first time in the near-infrared band, which is expected to provide a frontier route for multifunctional optical displays, high-level optical information encryption, and large-capacity full-duplex communication."}],"publication":"Advanced Photonics","issue":"05","doi":"10.1117/1.ap.8.5.056006","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.researching.cn/Articles/OJf9b235a7c5a0a3bf","open_access":"1"}],"intvolume":"         8","article_type":"original","date_updated":"2026-08-31T05:48:43Z","publication_status":"published","publication_identifier":{"issn":["2577-5421","2577-5421"]},"author":[{"first_name":"Guocui","last_name":"Wang","full_name":"Wang, Guocui"},{"full_name":"Geromel, René","last_name":"Geromel","first_name":"René"},{"first_name":"Qunshuo","last_name":"Wei","full_name":"Wei, Qunshuo"},{"last_name":"Zhao","first_name":"Ruizhe","full_name":"Zhao, Ruizhe"},{"last_name":"Li","first_name":"Xiaowei","full_name":"Li, Xiaowei"},{"id":"30525","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas"},{"full_name":"Huang, Lingling","first_name":"Lingling","last_name":"Huang"}],"title":"Asymmetric multi-channel holography by cascaded plasmonic Janus metasurfaces","year":"2026"},{"status":"public","user_id":"16199","volume":8,"_id":"67146","publisher":"American Physical Society (APS)","citation":{"mla":"Huo, Xunqin, et al. “Near-Bandgap Harmonic Generation in Solids from Multiple Scattering Revealed by Complex Quantum Trajectories.” <i>Physical Review Research</i>, vol. 8, no. 3, 033303, American Physical Society (APS), 2026, doi:<a href=\"https://doi.org/10.1103/l939-jglf\">10.1103/l939-jglf</a>.","ama":"Huo X, Liu X, Yang S, Song X, Meier T, Yang W.

Here, we systematically quantify the irradiance-dependent behavior of ordered mesoporous In2O3 under visible light illumination. Photoconductivity measurements reveal two distinct irradiance regimes consistent with trap-limited transport at low power and recombination- or saturation-limited transport at high power. Gas sensing experiments towards CO and H2 show a pronounced non-monotonic response, reaching maximum responses of 0.74 for 135 ppm CO at 67 mW cm−2 and 0.64 for 90 ppm H2 at 11 mW cm−2, followed by strong suppression at higher irradiance. Illumination also accelerated the response kinetics. At 60 ppm, t90 decreases from 96 to 12 s for CO and 141 to 27 s for H2, corresponding to an 8- and 5-fold faster response time, respectively. Near-ambient pressure-XPS under controlled atmosphere and density functional theory calculations indicate defect-mediated excitation. Oxygen vacancy states and illumination-induced modification of surface oxygen species govern this behavior. The results establish irradiance as a critical mechanistic parameter that determines whether In2O3 operates in a surface-controlled or bulk photoconductive regime. These findings highlight the need to explicitly optimize and report irradiance in illuminated gas sensor studies, and not only the power consumption of the light source.","lang":"eng"}],"issue":"7","publication":"ACS Sensors","doi":"10.1021/acssensors.6c01100","language":[{"iso":"eng"}],"article_number":"acssensors.6c01100","intvolume":"        11","article_type":"original","date_updated":"2026-10-15T08:04:24Z","publication_status":"published","author":[{"last_name":"Voth","first_name":"Sven","full_name":"Voth, Sven"},{"first_name":"Zhenyu","last_name":"Zhao","full_name":"Zhao, Zhenyu"},{"full_name":"Baier, Dominik","last_name":"Baier","first_name":"Dominik"},{"full_name":"Glass, Alexandra","last_name":"Glass","first_name":"Alexandra"},{"first_name":"Hossam","orcid":"0000-0002-4945-1481","last_name":"Elgabarty","full_name":"Elgabarty, Hossam","id":"60250"},{"full_name":"Sandberg, Oskar J.","last_name":"Sandberg","first_name":"Oskar J."},{"full_name":"Grundmeier, Guido","first_name":"Guido","last_name":"Grundmeier","id":"194"},{"orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael","full_name":"Tiemann, Michael","id":"23547"},{"full_name":"Smått, Jan-Henrik","first_name":"Jan-Henrik","last_name":"Smått"},{"full_name":"Anttu, Nicklas","first_name":"Nicklas","last_name":"Anttu"},{"last_name":"de los Arcos","first_name":"Teresa","full_name":"de los Arcos, Teresa"},{"full_name":"Weinberger, Christian","first_name":"Christian","last_name":"Weinberger","id":"11848"}],"publication_identifier":{"issn":["2379-3694","2379-3694"]},"title":"Role of Irradiance in Light-Activated In<sub>2</sub>O<sub>3</sub> Gas Sensors: Why More Light Is Not Always Better","year":"2026","project":[{"name":"Exploration of optoelectronic properties of metal oxides used in gas sensors and solar cells","_id":"1130"}],"citation":{"mla":"Voth, Sven, et al. “Role of Irradiance in Light-Activated In<sub>2</sub>O<sub>3</sub> Gas Sensors: Why More Light Is Not Always Better.” <i>ACS Sensors</i>, vol. 11, no. 7, acssensors.6c01100, American Chemical Society (ACS), 2026, doi:<a href=\"https://doi.org/10.1021/acssensors.6c01100\">10.1021/acssensors.6c01100</a>.","bibtex":"@article{Voth_Zhao_Baier_Glass_Elgabarty_Sandberg_Grundmeier_Tiemann_Smått_Anttu_et al._2026, title={Role of Irradiance in Light-Activated In<sub>2</sub>O<sub>3</sub> Gas Sensors: Why More Light Is Not Always Better}, volume={11}, DOI={<a href=\"https://doi.org/10.1021/acssensors.6c01100\">10.1021/acssensors.6c01100</a>}, number={7acssensors.6c01100}, journal={ACS Sensors}, publisher={American Chemical Society (ACS)}, author={Voth, Sven and Zhao, Zhenyu and Baier, Dominik and Glass, Alexandra and Elgabarty, Hossam and Sandberg, Oskar J. and Grundmeier, Guido and Tiemann, Michael and Smått, Jan-Henrik and Anttu, Nicklas and et al.}, year={2026} }","ama":"Voth S, Zhao Z, Baier D, et al.
