| 摘 要： | 用时间分辨的激光诱导荧光光谱方法测量了10—300K温度范围内Ni2+:BeAl2O4晶体的红外荧光光谱和荧光寿命。通过荧光寿命的温度变化特性分析,得出3T2g态的内禀辐射衰减寿命为123±7.2μs。无辐射弛豫的Mott激活能为1147cm-1,并导出了此晶体发光量子效率随温度的变化关系式。Ni2+:BeAl2O4关键词：

| Abstract: | The Laser induced fluorescence spectra and excitation decay process of Ni2+ doped with chrysoberyl were studied in temperature rang of 10 K to 300 K. It was shown that the intrinsic radiative lifetime of 3T2g state is 123±7.2 μs. Mott activation energy is 1147 cm-1. Ni2+:BeAl2O4 Crystal has considerable high radiative rate and luminescence efficiency at room temperature and is a possible good candidate for making tunable laser. |
