초록

In this study, Ce3+/Tb3+ co-doped borophosphate glasses were synthesized using the conventional meltquenching method. The luminescent properties and energy transfer mechanisms between Ce3+ and Tb3+ ions were systematically investigated under both ultraviolet (UV) and X-ray excitation. Among the compositions, Ce:4 Tb glass exhibited excellent scintillation performance, with integral scintillation efficiencies reaching approximately 63 % and 61 % relative to commercial SG101 commercial glass and Bi4Ge3O12 (BGO) crystal scintillators, respectively. In addition, it achieved a high spatial resolution of 57.2 lp/mm, comparable to the 57.8 lp/mm resolution of commercial YAG:Ce crystal. These findings highlight the strong potential of Ce:4 Tb glass for advanced X-ray imaging application.
