Abstract:
The influence of different doses of $\gamma$-radiation from a $^{137}$Cs 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 $\gamma$-irradiation dose is presented. It is established that nanoparticles of the AgInS$_{2}$/ZnS system retain their photoluminescence properties and colloidal stability at the absorbed dose up to 6 $\times$ 10$^3$ Gy (with respect to water). The residual photoluminescence is retained until the absorbed dose is 10$^6$ Gy (with respect to H$_2$O). It is shown that AgInS$_{2}$/ZnS nanocrystals can be used in medical and biological studies, which call for enhanced resistance to $\gamma$-radiation.
