| 摘 要： | 本文通过溶胶－凝胶方法法制备了掺Ｔｂ＾３＋和Ａｌ＾３＋的硅基玻璃，并研究了Ａｌ＾３＋对Ｔｂ＾３＋发光性能的影响，结果显示Ａｌ＾３＋对Ｔｂ＾３＋的发射峰的位置没有明显影响，但通过溶胶－凝胶方法掺Ａｌ＾３＋后，所有样品中Ｔｂ＾３＋的发光强度都明显增加，掺８％－１０％的Ａｌ＾３＋的Ｔｂ－硅基玻璃中Ｔｂ＾３＋的发光强度是不掺Ａｌ＾３＋的Ｔｂ－硅基玻璃中的５倍，我们推测Ｔｂ＾３＋和Ａｌ＾３＋能级之间的关系对于能量传递是比较合适的，Ａｌ＾３＋的作用是更有效地吸收能量并完全地转移给Ｔｂ＾３＋。

| Abstract: | The silica glasses doped with Tb 3+ and Al 3+ inoes was synthesized through Sol Gel process in this paper.The effect of Al 3+ on luminescence properties of Tb 3+ were studied.The results show that no obvious effect of Al 3+ on the emission peak position of Tb 3+ ,but the emission intensity of Tb 3+ doped Al 3+ by sol gel process increased obviously for all samples.The emission intensity of 1% Al-99% SiO 2 glass was 5 times larger than that of 100% SiO 2 glass.We concluded that the relation between the energy levels of Tb 3+ and the energy levels of Al 3+ may be appropriate for the energy transfer,the function of Al 3+ was to absorb efficiently energy and to transfer fully to Tb 3+ . |
