Polarization and intensity analysis of lateral scattering light from nanoparticles

The characteristics of laterally scattered light from nanoparticles can be experimentally studied by polarization imaging technology. This paper compares and analyzes the differences in polarization between nanoparticles and microparticles. Then, the influence of the incident light intensity on scattered light and the degree of polarization is studied. It is found that, when the concentration of nanoparticles is constant, the degree of polarization of scattered light is not affected compared with the scattered light intensity. Finally, the variation law of nanoparticle concentration and polarization is studied. It is found that, with the increase of particle concentration, the polarization of lateral scattered light increases and then decreases.
