摘要
利用光学显微镜观察了Bridgman法生长的PbWO4晶体 (0 0 1)晶面的腐蚀形貌 ,讨论了位错蚀坑的形态特征 ,分布规律以及与晶体结晶习性的关系 ,同时还观察了亚晶界的形态 。
Etching morphology of (001) faces of PbWO 4 crystal grown by Bridgman method was observed by using optical microscope.Morphological features and distribution regularity of dislocations were discussed.The relation between features of etch pit and crystallization habit of crystal was revealed.Respectively,the formations of dislocation and sub grain boundary were also studied in this paper.
