| Popis: | The method of partially depolarized dynamic light scattering is applied to measurements of gold nanorods dimensions in liquids using translational and rotational diffusion coefficients. Compared with the known methods, the new method makes it possible to lower the power of the existing laser radiation and to increase the data set for solving the inverse problem. Nanorod lengths calculated from the diffusion coefficients are in agreement with TEM data. Aspect ratios calculated from extinction spectra in the plasmon resonance domain are in better agreement with TEM. |
