中文摘要采用提拉法生长Y3Al5O12(YAG)晶体和Yb3+掺杂原子数分数分别为5%, 10%, 15%, 20%, 25%, 50%和100%的Yb∶Y3Al5O12(Yb∶YAG)晶体。系统表征和分析了Yb3+掺杂浓度对拉曼光谱的影响。随着Yb3+掺杂浓度的增加,晶体的振动模式没有明显的变化,晶体结构没有改变;在370 cm-1和785 cm-1附近,振动吸收峰的半峰全宽逐渐增大。分析得出,Yb3+掺杂浓度对晶体的晶格、对称性、荧光寿命均有影响,从而可能影响到晶体的光谱和激光性能。; Y3Al5O12 (YAG) and Yb∶Y3Al5O12 (Yb∶YAG) single crystals with Yb3+ doping atomic number fraction of 5%, 10%, 15%, 20%, 25%, 50%, and 100% were grown by the Czochralski method. The effects of Yb3+ doping level on the Raman spectra were studied. There were little abrupt change of the vibration modes and little change of the crystal structure with the increase of Yb3+ doping level in Yb∶YAG crystals; but the fullwidth at half maximum of absorption peak centered at 370 cm-1 and 785 cm-1 increased with the increase of Yb3+ doping level. The results show that Yb3+ doping level influences the lattice, symmetry and fluorescence lifetime of Yb∶YAG crystals and this may influence the spectrum and lasing properties of the crystals.
