摘要
用提拉法生长了质量较高的Ａｌ∶Ｂｉ１２ＳｉＯ２０和Ｃｒ∶Ｂｉ１２ＳｉＯ２０（简称Ａｌ∶ＢＳＯ和Ｃｒ∶ＢＳＯ）晶体，测定了掺杂ＢＳＯ晶体的吸收光谱。首次发现：Ａｌ∶ＢＳＯ（摩尔比）为０．１％的晶体的透过率（８０％）远高于纯ＢＳＯ晶体的透过率（７０％）；Ｃｒ∶ＢＳＯ晶体中除Ｃｒ３＋外。
High quality Al∶Bi 12 SiO 20 (Al∶BSO)and Cr∶Bi 12 SiO 20 (Cr∶BSO)crystals were grown by CZ technique.The absorption spectra of doped BSO crystals were measured.It was found that the transmission of Al∶BSO(0.1% mol Al 2O 3)is up to 80%,higher than that of pure one(70%) with the same thickness,and there were a few Cr 4+ ions in Cr∶BSO besides Cr 3+ .
