Abstract

Paper contains results of investigation of nanosheets by modificated DLS technique. The modified method of dynamic light scattering is based on an additional estimation of complexity of the radiation scattered at different angles for the horizontal and vertical polarization of the input beam. It is shown that the complexity of the fluctuations of scattered field depend on the angle of scattering and polarization of the laser beam and allow us to qualitatively evaluate the sphericity of the particles. To quantify complexity, correlation exponent of fluctuations of the intensity of the field of scattered coherent optical radiation was used, respectively. Сorrelation exponent is determinated from the slope of the correlation integral. It was found that the slope of the correlation integral is not linear and depends on the sphericity of nanoparticles.
