人工晶体 Yb:YAG晶体 色心 荧光寿命 浓度猝灭 synthetic crystal Yb:YAG crystal color center fluorescence lifetime concentration quenching
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Yb2O3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10 at.-%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.
