中文摘要：

为进一步提高Er^3＋1．53μm波段的光谱特性，在Er^3＋^4I11／2→4I/13/2和Ce3＋：2F5／2→F7／2跃迁间存在能量失配（1400cm。附近）的Er^3＋／Ce^3＋共掺碲酸盐（TeO2-Bi203-TiO2）玻璃中引入了高声子能量SiO2组分。测试分析了不同Si02组分含量下的Er^3＋吸收光谱、上转换发光谱、1．53btm波段荧光谱、荧光寿命、放大品质因子和玻璃样品的热性能。结果表明：由于增强的Er^3＋／Cd^3＋离子间能量传递，当玻璃样品中SiO2含量达到9％（摩尔分数）时，Er^3＋的1．53μm波段荧光强度得到显著提高。同时，荧光半高宽随SiO2组分含量相应展宽，而玻璃热稳定性随之提高。

英文摘要：

In order to further improve the 1.53/zm band spectroscopic properties of Era＋ , a high phonon-energy oxide of SiOz was introduced into the Era＋/Ce3＋ co-doped tellurite glass （TeOz--Biz O3--TiOz ） with the energy mismatch （--1 400 cm-1 ） between the Er3＋4I11/2→4I/13/2和Ce3＋：2F5/2→F7/2 transitions. The absorption spectra, up-conversion emission spectra, 1.53μm band fluorescence spectra, fluorescence lifetimej amplification quality factors of Era＋ and DSC curves of glass samples with different SiOz contents were analyzed. The results indicate that the 1.53 μm band fluorescence intensity of Era＋ is im- proved when the SiOz content in the glass is 9 %（in mole} due to the enhanced energy transfer between Era＋ and Ce3＋ ions, and its fluorescence full width at half maximum is broadened and the thermal stability of glass host is improved accordingly with the SiOz content.
