The effect of different doses of γ-radiation from a 137Cs source on photoluminescence of Ag-In-S nanocrystals covered with a shell of wider bandgap ZnS was investigated. The dynamics of changes in the nanocrystals photoluminescence depending on the dose of γ-radiation was shown. It was established that the AgInS2 / ZnS nanoparticles retain their photoluminescent properties and colloidal stability upon reaching the absorbed dose of 6 • 10^3 Gy (to water). Residual photoluminescence persisted when the absorbed dose reached 10^6 Gy. It was shown that AgInS2 / ZnS nanocrystals can be used in medical and biological studies in which increased resistance to gamma radiation is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
