In the present work, an attempt to obtain quantum dots with a high quantum luminescence yield has been made. For this purpose, the existing methods of synthesis have been studied; approbation of availability and reproducibility of the results and possibility of obtaining luminescent QD samples in the required spectral region has been made. The optical characteristics, the influence of the synthesis conditions, the possibility of using nanostructured materials for sensitization of solar cells have been studied.

The effect of light irradiation on the spectral-luminescent characteristics of some rhodamine dyes with a carboxyl group in solvents of various natures was studied. It has been established that under the influence of light irradiation in aqueous solutions of selected dyes, a decrease in the intensity of absorption and fluorescence with a simultaneous hypsochromic shift of the electronic spectra is observed.Under the same conditions, discolored solutions of rhodamine dyes in a binary solvent mixture of 1% water + 99% DMSO are reduced in color and, accordingly, absorbing and fluorescent capacity. The observed phenomenon is explained by the transition of molecules …
