摘要
测量了Ｃｒ３＋和ＲＥ３＋（Ｔｍ３＋，Ｈｏ３＋，Ｎｄ３＋）共掺的ＹＡＧ晶体的吸收谱、荧光谱和Ｃｒ３＋的荧光衰减曲线．计算了Ｃｒ３＋向ＲＥ３＋能量转移的效率和速率．它是依Ｈｏ３＋、Ｎｄ３＋，Ｔｍ３＋递增的，提出比较能量转移效率大小的简便方法．
The absorption and fluorescence spectra of (Cr, RE) YAG crystals and the the fluoresoent decay curves of chromium ions are measured.It is proved that the rate and efficeincy of energy transfer from Cr3+to RE are increased in order of Ho, Nd, and Tm· A simple method for the comparison of energy transfer efficiency is proposed.
