  bibo_abstract:
  - Second harmonic generation (SHG) spectroscopy is a recently developed technique
    for the investigation of surface properties of particles. To apply the method
    to technical colloidal systems, the dependences of several experimental parameters
    on the signal have to be studied. In this work the influence of particle concentration
    on the SHG signal from the surfaces of colloids (polystyrene beads in a size range
    of 0.1 μm to 2.9 μm) is investigated. A simple model, based on Lambert–Beer’s
    law, to describe the measured dependences is derived. The model agrees with the
    experimental observations for particles smaller 1.1 μm and with a small modification
    also for larger particles. Based on the new model an analytical equation for determining
    the optimum concentration, where highest signals in colloidal SHG spectroscopy
    measurements are obtained, is derived. @eng
