摘要：
Photoluminescence and X-ray-induced scintillation properties of xCe:20BaO-15Gd(2)O(3)-65SiO(2) (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 Ce3+. The P-6(7/2)-S-8(7/2) 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.
