We prepared glass samples with a chemical composition of 30KPO 3 70Al(PO 3) 3 by the melt quenching method. As a radio-photoluminescence (RPL) emission center, Ag 2 O (0, 0.1, 0.3, 1.0 and 3.0%) was doped in these glasses. Before X-ray irradiation, Ag-doped samples showed a blue luminescence upon 254 nm excitation while they exhibited an orangish luminescence upon 304 nm excitation after X-ray irradiation. We evaluated dosimeter properties such as dose response properties of RPL, fading and thermally stimulated luminescence (TSL) glow curves. Dose response function in RPL emission indicated the lower detection limit of 100 mGy. In addition, TSL glow curve of Ag-doped 30KPO 3 70Al(PO 3) 3 showed that accumulated carriers in the samples were released at around 85°C and easily re-excited at room temperature.
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.
