This study concerns alkaline fluorides such as CaF2 and BaF2 contained in gadolinium phosphate glass doped with CeF3, which were synthesized using a melt-quenching technique. Ce3+ was activated in both glasses and a comparative study of their optical, luminescence and scintillation behaviors was conducted. The results found that the higher atomic weight of BaF2 glass makes higher density compared with CaF2 glass, resulting in more integral scintillation efficiency. The quantum yield of BaF2-glass (PLZGdBafCe0.5) is also higher than that of CaF2-glass (PLZGdCafCe0.5). Energy transfer efficiency from Gd3+ to Ce3+ shows similar values, reflecting that the higher photoluminescence intensity of BaF2-glass comes from the efficiency of the luminescence center (Ce3+ ion). Photoluminescence and scintillation decay times were measured and found to be in the range of nanoseconds. XANES measurement was used to confirm the oxidation state and ratio between Ce3+/Ce4+. Moreover, the practical application of the glass scintillator was succeeded by micro-imaging using synchrotron X-ray. © 2025 Elsevier Ltd and Techna Group S.r.l.
