We prepared a 1Eu2O3–13Bi2O3–12ZnO–74TeO2 glass (PG) and its glass ceramics (GC340, GC350, and GC360) and evaluated their luminescence properties for scintillators. GC340, GC350, and GC360 were obtained by heat treatment of PG for 24 h at 340, 350, and 360 ℃, respectively. Distinct luminescence peaks derived from the radiative transition between 4f levels of Eu3+ appeared in PG, GC340, GC350, and GC360 when excited by X-rays or visible light. The scintillation intensity was enhanced by increasing the heat treatment temperature of PG, whereas the quantum yield in photoluminescence was decreased by heat treatment. The results suggest that the energy transfer efficiency in the host material might be increased by heat treatment.
