| 摘 要： | 采用熔融-晶化法制备了Tb3+掺杂的CaMoO4为主晶相的透明钼酸盐玻璃陶瓷。利用DSC、XRD、SEM确定了该体系玻璃样品的最佳热处理制度：715℃保温2.5 h；随着热处理时间的增加，玻璃陶瓷中的晶粒尺寸逐渐变大；利用UV-Vis-NIR得到样品玻璃陶瓷在可见光区的透过率可达80%；并利用荧光光谱讨论了在相同热处理条件下，不同Tb3+掺杂浓度对玻璃陶瓷样品发光性能的影响，研究表明Tb3+掺杂浓度为7.0mol%时样品的荧光强度最大。

| Abstract: | Tb3+ doped transparent molybdate glass ceramics containing CaMoO4 were successful fabricated by melt-quenching technique. The optimal heat-treated system for the glass sample was determined by DSC,XRD and SEM(715℃ for 2. 5 h). The grain size of the glass ceramics gradually increased with the increasing of heat treatment time. The UV-Vis-NIR spectra indicated that the sample transparency was approximately up to 80% in visible light range. The effect of different Tb3+ doping concentration on the luminescence properties of the glass ceramics under the condition of the same heat treatment by fluorescence spectrum. The experimental result indicated that the Tb3+ doping concentration was 7. 0 mol%, the sample has the maximum fluorescence intensity. |
