研究了不同环境温度下晶体LaOF和非晶体SiO2纳米体系中掺杂Tm3+ 离子的荧光光谱。结果表明，在20~300 K的温度范围内，荧光谱线的宽度、强度以及谱线位置均随温度的升高而变化。发光离子的局域环境直接影响荧光光谱对环境温度的依赖程度：SiO2中发光离子的荧光寿命受温度影响较小，而位于晶相环境LaOF中离子的荧光寿命则显示较强的温度依赖特性，在脉冲激光激发条件下，研究了3H4能级荧光寿命随温度变化的规律。

Fluorescence spectra of Tm3+-doped LaOF and SiO2 nanosystems at different temperatures are investigated, which show that line width, intensity of fluorescence and spectra position all change with the increase of temperature in the range of 20~300 K. Dependency on temperature of fluorescence spectra is influenced directly by local environment. Fluorescence lifetime of active ions in SiO2 uncrystal phase is less affected, while it is largely affected in LaOF crystal phase ambient. The rule reliance upon temperature of 3H4 lifetime is studied under pulsed laser excitation.
