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.

note = "Funding Information: RL spectra of Ce:SABG glasses and BGO crystal as measured in similar conditions are displayed in Fig. 5.

Apparently, all Ce:SABG glasses showed good scintillation efficiency higher than that of 30% of BGO obtained for our previously reported Ce-doped SiO2?B2O3?Al2O3?Gd2O3 glass [6]. High scintillation efficiency comparable to the BGO crystal obtained for a Ce:SABG10 glass in this work is higher than that of 87% of BGO reported for Ce -doped SiO2?B2O3?BaF2-Lu2O3?Gd2O3 glass [13]. The red shift of RL spectra with increasing Gd2O3 content in Ce:SABG glasses is also obtained in the same trend with the PL spectra, as mentioned above. A decrease of scintillation efficiency for higher Gd2O3 containing glasses is observed, attributing to self-absorption effect due to an enhanced overlap between the PL and PLE spectra as shown in Fig. 2, supported also by the low-energy shift of UV cut-off position (see Fig. 1).The authors acknowledge the financial support provided by King Mongkut's University of Technology Thonburi through the ?KMUTT 55th Anniversary Commemorative Fund?, the National Research Council of Thailand(NRCT no. 1948) and the National Natural Science Foundation of China (NSFC no. 51872308).
