Abstract:

The anisotropy of the optical properties of CdSe quantum nanoplates is investigated, using the methods of absorption spectroscopy. It is experimentally established that the optical properties of the quantum nanoplates are anisotropic. Spectral dependences are obtained for the absorption anisotropy of ensembles of nanocrystals ordered in a stretched polymer film. A technique has been developed for creating elastic polymer films made from polyvinyl butyral with a high concentration of quantum nanoplates.

Keywords:
