摘要

采用直径-重量自动控制方法，采用zzohralski技术制备了掺杂钌、锰和钌加锰的锗酸铋(BGO)单晶。研究了掺杂对BGO单晶光致、磁光及全息性质的影响。结果表明，在热退火和紫外光均匀照射下，掺杂样品的透射光谱发生了明显的改变，且光致变色效应完全可逆。测量了磁光旋光度，计算了可见光谱范围内的Verdet常数。成功地记录了633 nm的全息光栅。

Optical, magneto-optical, and holographic study of Bi4Ge3O12 crystals doped with transition elements

Bismuth germanate Bi4Ge3O12 (BGO) single crystals doped with ruthenium, manganese and ruthenium plus manganese are grown by Czohralski technique with automatically diameter-weight control method. The effect of doping on the light-induced, magneto-optical and holographic properties of BGO single crystals is studied. It was found that the optical transmission spectrum of doped samples is modified strongly under thermal annealing and homogeneous illumination with UV light as well as the photochromic effect is fully reversible. The magneto-optical rotation was measured and Verdet constant was calculated at visible spectral range. Holographic grating are successfully recorded at 633 nm.
