| 摘 要： | 研究了不同掺杂浓度的Yb∶YAG晶体氢气退火前后的色心吸收 ,发现随着Yb2 O3 浓度的增加 ,色心浓度并不增加。测量了退火前后不同浓度晶体的荧光光谱和荧光寿命 ,指出低浓度掺杂时 ,色心对发光强度和荧光寿命没有猝灭作用 ,只有在掺杂浓度大于 1 0at. %时 ,色心吸收的加强对发光强度和荧光寿命才有明显猝灭作用

| Abstract: | The color center absorption properties of as grown and H 2 annealing Yb:YAG with different Yb 3+ doped concentration have been studied,and its concentration is not consistent with doping concentration of Yb 2O 3. The fluorescence spectra and fluorescence lifetime of Yb:YAG are measured. It is only when the doped concentration more than 10at. % that the color center has a evident quenching effect on fluorescence intensity and fluorescence lifetime of Yb:YAG. |

| Keywords: | synthetic crystal Yb:YAG crystal color center fluorescence lifetime concentration quenching |
