摘要：
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 that the luminescence spectrum of CuInS2/ZnS quantum dots consists of two components, which are described by Gauss type function and connected with different types of defects into nanoparticles. The parameters of these two components as luminescence peak maximum, FWHM and amplitude are changed under heat treatment. CdSe/ZnS nanoparticles spectra shifted to the red region; the average thermal spectrum shift is 0.065 nm per degree.
