Tm3+/Ho3+共掺硫卤玻璃的2.00 μm荧光特性研究
Source abstract
Abstract
通过真空熔融淬冷法制备了不同浓度Tm3＋/Ho3＋离子共掺的70GeS2-20In2S3-10CsI玻璃样品,分析了样品的热稳定性及拉曼光谱,测试了样品的吸收光谱以及808 nm激光泵浦下Ho3＋：5I7→5I8辐射跃迁对应的2.00μm荧光光谱特性.结果表明：Tm3＋离子掺杂浓度为0.25mol%时,随着Ho3＋离子掺杂浓度从0.05mol%增加到0.125mol%,Tm3＋离子在1.86μm的发光强度逐渐减弱,Ho3＋离子2.00μm荧光明显增强,表明Tm3＋/Ho3＋离子之间存在有效的能量转移.
