Синтез и характеризация наночастиц CuIn-=SUB=-2-=/SUB=-S

Abstract

CuInS2 nanoparticles were synthesized and coated with ZnS. The absorption and luminescence spectra of nanoparticles, as well as the dependencies of the luminescence spectra on temperature, the In/Cu ratio, and particle coating were obtained. It was shown that the properties of nanoparticles change over time after synthesis. The ripened CuInS2 / ZnS nanoparticles luminesce in the range of 600–850 nm. The coating of nanoparticles with a shell significantly increases the luminescence intensity. The obtained nanoparticles can be used as temperature sensors at deep incorporation into biological tissue.
