Photoluminescence and X-ray-induced scintillation properties of xCe:20BaO-15Gd2O3-65SiO2 (x = 0, 0.01, 0.05, 0.1, 0.5) glasses were investigated. The glass samples emitted light via energy transfer from Gd3+ in the host to the Ce3+ ion. The 6P7/2–8S7/2 relaxation of Gd3+ was confirmed notably in the undoped glass sample, but the emission due to Gd3+ disappeared upon the addition of Ce. Furthermore, the decay time constant of Gd3+ decreased with increasing Ce concentration.
