| 摘 要： | 研究了Er3+/Yb3+共掺、Tm3+/Yb3+共掺、Er3+/Yb3+/Tm3+共掺碲酸盐玻璃在970nm抽运下的荧光光谱和上转换光谱性质，测试了Er3+离子的4I11/2和4I13/2能级荧光寿命变化情况.结果发现Er3+/Yb3+/Tm3+共掺碲酸盐玻璃的常规荧光谱线在1450—1700nm区域明显加宽，并在1630nm有一荧光峰，可能是Tm3+：1G4→3F2跃迁产生.上转换发光研究表明，由于碲酸盐玻璃声子能量低的缘故，三种共掺系统下都存在上转换发光现象.在Er3+/Yb3+/Tm3+共掺中，上转关键词：Er3+/Yb3+/ Tm3+共掺碲酸盐玻璃荧光上转换光谱

| Abstract: | The fluorescence and up-conversion spectrum of Er3+/Yb3+, Tm3+/Yb3+, Er3+/Yb3+/Tm3+-codoped tellurite glasses pumped by a 970nm laser diode has been studied. The lifetimes of Er3+:4I11/2 and Er3+: 4I13/2 levels have been measured. It is found that the fluorescence width in the range of 1450—1700nm in Er3+/Yb3+/Tm3+-codoped tellurite glass has been broadened clearly. There is a fluorescence peak at 1630nm which is probably due to Tm3+:1G4→3F2 transitions in Er3+/Yb3+/Tm3+-codoped tellurite glass. Up-conversion phenomena exist in all the three kinds coped tellurite glasses because of its lower phonon energy of host. The addition of Tm3+ in Er3+/Yb3+-codoped tellurite glasses quenches the up-conversion efficiency of Er3+:4S3/2 green and Er3+:4F9/2 red emissions. The quenching effect is due to the energy transfer between Er3+ and Tm3+, especially the cross-relaxation process among them. |
