Abstract

Ce³⁺-doped glasses with composition of (65-x)SiO₂ − 20Al₂O₃ –15BaF₂ -xGd₂O₃ (x = 5, 10, 15, 20 and 25) were synthesized under CO atmosphere by melt-quenching method. The photoluminescence (PL) emission due to Ce³⁺: 5d₁ → 4f transition was red-shifted with increasing Gd₂O₃ content. The acceleration of PL decay was observed with increasing Gd₂O₃ content. The scintillation efficiency of about 100% of the Bi₄Ge₃O₁₂ scintillator was obtained for a 10%Gd₂O₃ containing glass while a high light yield (LY) of 2050 photons/MeV and energy resolution of 15.8% at 662 keV γ rays was obtained for a 15%Gd₂O₃ containing glass. The integrating-time dependence of LY value and LY ratio (α/γ ratio) under excitation with α- and γ-rays were also measured.
