摘　　要：采用溶胶凝胶法制备了离子掺杂的锌硼硅体系长余辉发光玻璃。通过对发光玻璃进行X-射线衍射分析、差热分析、红外光谱分析，考察了玻璃的非晶结构以及合成过程中物理化学变化，研究了Tb^3＋掺杂浓度对玻璃的长余辉性能的影响。结果表明，铽离子浓度为10％时制得余辉性能良好的发光玻璃。Tb^3＋-doped ZnO-B2O3-SiO2 long lasting glass preproducted by sol-gol method in this resreach.Amorphous structure, synthetic process and the physical-chemical reactions of glass were detected by X-ray diffraction analysis, ifferential thermal analysis and infrared spectroscopic analysis. Meanwhile the effect of Tb^3＋ concentration on phosphorescence was researched.The results was showed that phosphorescence was the most excellent when the concentration of Tb^3＋ was 1.0%.
