中文摘要：

本文采用导模提拉法成功生长了Tb3Sc2Al3O12（TSAG）晶体，并对所生长晶体进行了物相分析和单晶结构分析，探讨了多晶原料的烧结温度对晶体颜色的影响。Sc^3＋和Al^3＋的浓度分布测试表明，导模提拉法能较好地克服因分凝效应引起的Sc^3＋浓度分布不均，可以生长获得浓度分布均匀的TSAG晶体。磁光性能测试表明，Sc^3＋掺入对晶体在400—1100nm波长范围内的磁光性能影响不大，所生长TSAG晶体的费尔德常数仅比Tb3Sc2Al3O12（TSAG）晶体低6％～8％。

英文摘要：

Tb3Sc2Al3O12（TSAG） crystal was successfully grown by the edge-defined film-fed growth method. The crysal structure was determined by powder XRD and single crystal X-ray diffraction analysis. The influence of the sintering temperature of polyerystalline materials on the crystal colonr was also investigated. The results of Sc3＋ and A13 ＋ concentrations in crystal show that the uneven distribution of Sc3 ＋ in crystal induced by the segregstion effects can be restrainted by EFG method. The test results of the magneto-optical effect show that as-grown TSAG crystal still has high Verdet constant, which only 6% -8% lower than that of TAG crystal in the wavelength of 400-1100 nm.
