| 摘 要： | 利用高温熔融法制备了不同浓度的Tb3+掺杂硅酸盐玻璃，并分别测量了紫外和X射线激发时的发射光谱。光谱结果表明，不同浓度Tb3+掺杂硅酸盐玻璃在紫外和X射线激发时发光行为具有相似的浓度依赖关系：低浓度Tb4O7掺杂时主要以蓝光(5D3→7FJ)发射为主，而高浓度掺杂时以绿光(5D4→7FJ)发射为主。Tb3+发光强度与掺杂浓度的关系分析表明，5D3的浓度猝灭是电偶极-电偶极相互作用引起的, 而5D4的浓度猝灭是交换相互作用引起的。

| Abstract: | A series of concentration-varied Tb3+-doped silicate glasses were synthesized by the melt-quenching process. Photoluminescence and radioluminescence of Tb3+-doped silicate glasses were studied under UV and X-ray excitation, respectively. The similar concentration dependence of Tb3+ luminescence on its dopant concentration was obtained under both UV and X-ray excitation. That is, the blue emission (5D3→7FJ) dominates in the case of low concentration Tb3+-doped silicate glass, while the green one (5D4→7FJ) dominates in high concentration doping. The dependence of the intensity on Tb3+-dopant concentration indicates that the quenching of the 5D3 stat |
