| 中文摘要 | 采用提拉法生长了Yb^3＋掺杂量分别为5．4at％，16．3at％，27．1at％，53．6at％和100at％的Yb：Y3Al5O12晶体．系统地表征和分析了Yb^3＋掺杂量对晶体吸收光谱和荧光光谱的影响．随着Yb^3＋掺杂量的增加，各峰值吸收系数呈线性增加的趋势．应用Smakula公式计算了各吸收峰对应的振荡强度，并分析了Yb^3＋掺杂量对振荡强度的影响．当Yb^3＋掺杂量增加到27．1at％时观察到了荧光猝灭现象；当Yb^3＋掺杂量增加到53．6at％时，荧光光谱的线形发生了很大的变化。; Yb:Y3Al5O12 (Yb:YAG) single crystals with Yb3+ doping level of 5.4at%, 16.3at%, 27.lat%, 53.6at%, and 100at% were grown by the Czoehralski method. The effects of different Yb3+ doping level on the absorption spectra and fluorescence spectra were studied. The results showed that the real absorption coefficient of the absorption peaks increases linearly with the increasing of Yb3+ doping level in Yb:YAG crystals. Absorption band oscillator strengths of Yb:YAG crystals were calculated with Smakula formula and the effects of different Yb3+ doping level on the oscillator strengths were also studied. The concentration quenching of fluorescence was observed when the Yb3+ doping level reached 27.1 at% in Yb:YAG crystals. The shape of fluorescence spectra of Yb: YAG could be significantly influenced when the Yb3+ doping level is higher than 53.6at%. |
