摘要: 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CeO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.

Abstract: 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.

Key words: doped cerium bismuth silicon oxides (Ce:BSO), crystal growth, multi-position furnace
