摘要：
This paper presents the results of photoluminescence and X-ray induced scintillation properties of xCe:33.3BaO-66.6SiO(2) (x = 0, 0.05, 0.1, 0.5, 1.0, 2.0) glasses produced by the Floating Zone (FZ) method. We observed intense emission from 5d-4f transition of Ce3+ and the concentration quenching with the increase of Ce concentration in photoluminescence (PL) and scintillation properties. The lowest Ce-doped sample indicated the highest scintillation intensity in the X-ray induced scintillation measurement. The non-doped sample had the highest afterglow level, and the afterglow levels decreased with Ce addition amount. From these results, it was found to be in a trade-off relationship between the scintillation intensity the and afterglow characteristics in present samples.
