研制了Gd2O3摩尔分数可达30%、掺Ce3+的SiO2-B2O3-Al2O3-Gd2O3系统、高密度闪烁玻璃。研究了用BaO和La2O3取代Al2O3时玻璃的吸收光谱和荧光光谱等性能的变化，发现BaO在摩尔分数为10%时有着最佳的荧光性能，同时BaO或La2O3取代量的增加会使得激发谱和发射谱的峰值波长红移。在X射线激发下，该玻璃表现出闪烁性能，闪烁发光的中心波长比330 nm波长紫外光激发下的荧光中心波长红移了40 nm，显示了闪烁发光与荧光发光有着不同的发光机理。

Ce3+-doped scintillating glasses with up to 30%(mole fraction) Gd2O3 and high density in the system SiO2-B2O3-Al2O3-Gd2O3 have been prepared. Absorption and fluorescence properties of substitutions of Al2O3 by BaO and La2O3 have been investigated. Optimum luminescent intensity and absorption in these glasses is detected when the mole fraction of BaO is 10%. Meanwhile, substitutions of Al2O3 by BaO or La2O3 also lead to the red shift of the emission and excitation peak. Scintillating performance are shown under X-ray irradiation, but the result shows that the peak wavelength red shifts 40 nm compared with the peak of emission spectra under 330 nm ultraviolet light excitation suggests the different mechanism between fluorescence and scintillating light.
