摘　　要：介绍了用偏光显微镜对αＬｉＩＯ３特性的观察．研究了五种不同电极界面状态的八块晶体样品在ｃ向静电场作用下晶体的电导、空间电荷的沉积和分布．观察到由于αＬｉＩＯ３的空间电荷的输运形成的彩色准直条纹．此彩色条纹与光折变型光栅的衍射带之间有对应关系．Abstract This paper presents an account of our observation on characters of the α LiIO 3 by using a plorazation microscope. The conduction of crystal,the deposition and distribution of the space charges were studied for eight crystal specimens under the actions of the DC electric field in c direction with five different electrode interface states. The colored quasi straight bright lines were observed that formed through the transport of the space electric charges of α LiIO 3.There are a correspondence relation between it and the diffraction band of the photo refractive grating in the crystals, and the different interface states have exerted obvious influence on the ionic transport and crystal conduction in α LiIO 3.
