摘要：

In this work, we introduce a new setup and a method for characterizing anisotropic nanoparticles using a multi-angle polarization dynamic light scattering technique. This method is based on the measurement of the correlograms of scattered light intensity fluctuations both in the parallel and crossed polarizer configurations, and possibly concomitantly, from which the rotational and translational diffusion coefficients are extracted. By inversing the mathematical expressions of these coefficients, this approach allows the rapid determination of length and diameter of the anisotropic nanoparticles, enabling kinetic measurements. A comparison of experimental results obtained with this multi-angle depolarized DLS (DDLS) method to classical TEM images is discussed.
