测量了不同温度下Cr；Tm：YAC晶体的荧光光谱和荧光寿命，研究了温度对Cr3+→Tmn3+能量转移的影响。结果表明，随着温度不断升高，能量转移速率持续增加，能量转移效率先增加后下降，在120K出现极大值。
The fluorescence spectra and fluorescence lifetime of Cr; Tm: YAC crystals were measured at different temperatures. The effects of temperature on the energy transfer of Cr3 + → Tmn3 + were studied. The results show that as the temperature increases, the energy transfer rate continues to increase, and the energy transfer efficiency first increases and then decreases, reaching a maximum at 120K.
