“…On the other hand, the development of heavy-element glass scintillators has been progressing in recent years, and a few studies on some of them with light yield of more than 50% of the GS-20 scintillator have reported. [13][14][15][16] While these results support the potential of heavy-element oxide glasses as scintillators for X-and γ-ray detection, they also suggest that there is room for further material search. For the search of materials for such heavy-element oxide glasses, special glass making techniques are useful.…”

In this study, Sn-doped 10HfO2-10Al2O3-80SiO2 glasses were prepared using a xenon imaging furnace and their physical, optical, and scintillation properties were investigated. At the composition ratio, the specimens did not completely vitrify, and they were crystallized glasses that contained nanocrystals of c-HfO2. Raman spectra show the absorption bands due to Si–O–Hf bonds, and the band clearly indicated an effective molecular mingling of SiO2 and HfO2 components in the glass. Moreover, the energy dispersive X-ray spectroscopy maps suggested that the elemental distribution of this glass specimen is heterogeneous. In terms of optical properties of the glass, all of the specimens showed emission due to Sn2+, and their tendency to increase PL QY with increasing Sn concentration. The estimated luminescence from pulse height spectrum measurements under alpha irradiation was ~2500 ph/MeV, approximately 35% of the GS-20 glass scintillator counterpart.

“…In recent years, Ce-doped oxyhalide and halide glasses have attracted much attention because of advantages including a low synthesis temperature and a low phonon energy compared with oxide glasses. (48)(49)(50)(51)(52) In addition, Ce-doped oxyhalide glasses show high LYs compared with those reported for glass scintillators; for example, the LYs reported for Ce-doped BaF 2 -Al 2 O 3 -B 2 O 3 , (53) CsCl-Al(PO 3 ) 3 -CsPO 3 , (54) and CsBr-Al(PO 3 ) 3 -CsPO 3 (55) were 1800, 2100, and 2700 photons/MeV, respectively. In the case of halide glasses, Ce-doped ZnCl 2 -based glasses such as CsCl-CaCl 2 -ZnCl 2 (56) and CsCl-BaCl 2 -ZnCl 2 (57) showed high quantum yields (QY) of ~87.6 and ~75.7, respectively.…”

Ce-doped 20CsBr-20BaBr 2 -60ZnBr 2 glasses were synthesized by the conventional melt quenching method, and their photoluminescence (PL) and scintillation properties were investigated. In the PL and scintillation spectra, all the Ce-doped glasses showed broad emissions due to the 5d-4f transitions of Ce 3+ ions. Under 241 Am α-rays, the light yield of 0.05% Ce-doped glass was 40 photons/5.5 MeV-α.

Oxyfluoride‐based sodium‐aluminum‐phosphate glasses with a fixed 7 mol% content of Gd2O3 and various amounts of CeF3 were fabricated by the melt quenching process. The fabricated glasses (NAPGCe) were studied by physical, optical, scintillation, and light yield properties. In NAPGCe glasses, intense emission peaks were observed at 312 nm (6P7/2 → 8S7/2) for Gd3+ and 336 nm (5d → 4f) for Ce3+ ions in both photoluminescence (275 and 294 nm) and radioluminescence (X‐ray) spectra. Upon excitation with 275 nm ultraviolet radiation, a decrease in Gd3+ emission and an increase in Ce3+ emission intensity lead to efficient energy transfer (ET) from Gd3+ to Ce3+ ion in NAPGCe glasses. The bi‐exponential function was applied to fit the non‐exponential decay curves of NAPGCe glasses and then calculated their lifetimes in the order of fast (18.25–16.94 ns) and slow (72.99–67.74 ns) decay times. An overall integrated scintillation efficiency of about 67% was estimated for NAPGCe0.10 glass compared to bismuth germanate oxide (BGO:Bi4Ge3O12) crystal. Under 241Am α‐ray (5.5 MeV) source, the light yield of the NAPGCe1.00 glass was obtained by comparing it with a commercial Li‐glass scintillator (GS20), and it was found to be 26 photons MeV−1.
