Ｂｉ１２ＳｉＯ２０是一种优质的光折变晶体．但在地面生长掺Ｃｅ：ＢＳＯ晶体时遇到的主要问题是分凝系数远远＜１，导致晶体组分不均匀．本文采用在空间生长掺Ｃｅ：ＢＳＯ晶体的多工位炉进行地面晶体生长，测试了ＣｅＯ２浓度分布和掺Ｃｅ：ＢＳＯ晶体的透过率，以便同空间生长掺Ｃｅ：ＢＳＯ晶体进行比较．
Bi12SiO20 single crystals exhibit excellent photorefractive behavior. The main problem in growing doped Ce:BSO crystals on earth is low segregation coefficients that result in a poor chemical homogeneity of the crystals. In our experiments, Ce:BSO crystals were grown on earth in the multi-position furnace especially designed for growing single crystals in space. The dopant distribution and transmission spectra of Ce:BSO grown on earth were measured and compared with that of Ce:BSO crystals grown in space.
