Abstract

Manuscript is devoted to the comparison of CdSe/ZnS and CuInS₂/ZnS quantum dots thermosensitivity in the view of their applications as nanothermometers. It was found the luminescence spectrum of CuInS₂/ZnS quantum dots consists of two components, which are described by Gauss type functions and connected with different types of defects into nanoparticles. The heat treatments provide different effects such as spectral shifts, FWHM and amplitude for these too components. CdSe/ZnS nanoparticles spectra shifted to the red region; the average speed of spectrum shift is 0.065 nm per degree.
