Аннотация
The influence of different doses of γ-radiation from a 137Cs source on photoluminescence of nanocrystals of the Ag–In–S system with a shell of wider-gap ZnS semiconductor and without it has been investigated. The dynamics of change in the nanocrystal photoluminescence depending on the γ-irradiation dose is presented. It is established that nanoparticles of the AgInS2/ZnS system retain their photoluminescence properties and colloidal stability at the absorbed dose up to 6 × 103 Gy (with respect to water). The residual photoluminescence is retained until the absorbed dose is 106 Gy (with respect to H2O). It is shown that AgInS2/ZnS nanocrystals can be used in medical and biological studies, which call for enhanced resistance to γ-radiation.
