用高温熔融法制备了以SiO2-B2O3-Al2O3-Gd2O3为基质系统Ce3+掺杂的玻璃样品, 测试样品的密度、紫外——可见透射光谱、紫外激发光谱和主要的闪烁性能, 并且把一部分闪烁性能和PbWO晶体及BGO晶体做比较. 着重研究了不同Ce3+掺杂浓度与Gd3+ 离子的含量对玻璃样品闪烁性能的影响规律. 结果表明: 玻璃样品具有较大的密度; 样品的X射线激发发射光谱发射峰位置都在390 nm左右, 当Ce3+ 离子的掺杂浓度为1.0 mol%(摩尔分数)、Gd2O3含量为15 mol%时, 玻璃样品的发光峰强度达到BGO晶体发光强度的90%; 同样验证了Ce3+ 离子具有浓度猝灭效应; Gd3+可以敏化Ce3+离子发光, 但是Gd3+离子到达一定浓度时, 反而会产生猝灭效应, 降低了Ce3+ 离子的发光. Ce3+ 离子掺杂SiO2-B2O3-Al2O3-Gd2O3系统的闪烁玻璃有望替代闪烁晶体广泛应用于高能物理中.The SiO2-B2O3-Al2O3-Gd2O3 system based samples doping with rare earth Ce3+ ions (cations) are synthesized by high-temperature melting method. The effects on their density, transmission and scintillating properties are investigated. The results indicate that all the samples, especially those that have high densities, have good physical properties. The emission peak wavelengths of all samples excited by X-ray are at 390 nm. Increasing the concentrations of Ce3 + and Gd3+ ions has a positive effect on luminescence properties. However, when the concentration of Ce3+ ions arrives at 1 mol%, with the increase of the concentration of Ce3+, the emission peak decreases. When Gd3+ ions concentration reaches a certain value scintillating properties decreases with Gd3+ ion concentration increasing. The X-ray-induced luminescence intensity of the sample of SBAG4 is about 90% that of BGO crystal. Gd3+ ions can sensitize the luminescence of Ce3+, the best concentration of Ce3+ ions is 1 mol% and the best concentration of Gd3+ ions is 15 mol%. These samples are attractive for some physical applications.
