摘　　要：使用光浮区法成功生长出了高质量的Yb原子百分含量为5%的Yb∶Lu_2O_3晶体,对晶体生长的各项工艺参数进行了探索和优化。通过X射线粉末衍射测定了其单晶结构为立方结构,Ia空间群,进行了结构解析。利用X射线荧光光谱测定了它的化学成分,计算了Yb^(3+)离子和Lu^(3+)离子的有效分凝系数,分别为0.93和1.00。High quality 5% Yb3＋ doped Lu2O3 crystal was successfully grown by optical floating zone method.The growth parameters for the Yb∶Lu2O3 single crystal by the optical floating method were explored and optimized.Its crystal structure was determined to be cubic structure,Ia space group by X-ray powder diffraction（XRPD）and the structure was analyzed.Chemical composition was determined by Xray fluorescence（XRF）and the segregation coefficients of Yb3＋ion and Lu3＋ ion was calculated to be 0.93 and 1.00,respectively.
