摘要

In this study, the photoluminescence and radioluminescence properties of MnO-doped SnO-ZnO-P_2O_5 glasses are examined. We have confirmed that linear dose-dependence and radioluminescence emission decay depend on Mn~(2+) concentration. Energy transfer from donor Sn~(2+) center to acceptor Mn~(2+) center is observed in both photoluminescence and radioluminescence processes, and the energy transfer efficiency is more than 90% when the Mn~(2+)/Sn~(2+) ratio is 5. Since emission intensity of Mn~(2+) is higher than that of Sn~(2+) in radioluminescence compared to photoluminescence, it is suggested that energy transfer from the host matrix to Mn~(2+) center by X-ray occurred preferentially over energy transfer to Sn~(2+) center. The present results suggest that the conventional parity rule for photoluminescence is not always adaptable for radioluminescence, although emission-related energy levels are the same for both the processes.
