英文摘要	This report presents the luminescence and scintillation response of Ce3+-doped oxide glasses with high Gd2O3(30 mol%) content. The characteristic emission of Ce3+5d → 4f transition peaking around 380 nm was observed in its luminescence spectra under UV and X-ray excitation. Photoluminescence decay kinetics was governed by a few tens of nanoseconds decay time. The integral scintillation efficiency of about 22% of that of the Bi4Ge3O12scintillator was obtained under X-ray irradiation. The light yield and its dependence on the integration time were measured and compared with that of the Bi4Ge3O12crystal. The total mass attenuation coefficient at 662 keV γ-rays was also determined and compared with the theoretical one calculated using the WinXCom program. ? 2016 Trans Tech Publications, Switzerland.
