摘要

本文首次报道了Fe和Mn掺杂Bi4Ge3O12晶体的光吸收、光电导率和可见光折变特性。光吸收和光电导响应覆盖可见光和紫外线高达约4.0 eV。人们发现书写和擦除机制很复杂。讨论了光栅的起源，并报道了几种材料参数的计算。

Photorefractive Properties of Iron and Manganese Doped Bi4Ge3O12 Single Crystals

We report first results on the optical absorption, photoconductivity and visible photorefractive properties of Bi4Ge3O12 crystals doped with Fe and Mn. Optical absorption and photoconductivity response covers the visible and ultraviolet up to about 4.0 eV. The writting and erasure regimenes have been found complex. The origin of the gratings is discussed and calculations of several material parameters are reported.
