【摘要】 研究了PbM₀O₄单晶中的光散射现象,指出晶体中点缺陷的聚合体（空位团）和空位与位错交互作用构成的微观不均匀区是造成光散射的主要原因,探讨了空位与位错的数量、分布及共运动机制,并提出清除光散射中心的方法。更多还原

【Abstract】 The light scattering phenomena in PbMoO4 single crystal are studied.It is suggested that clusters of point defects (clusters of vacancies) and the microscopic non-uniform field caused by interaction between vacancies and dislocations be the main cause of light scattering. The number and distribution of vacancies and dislocations as well as their mechanism of motion are studied. A method of eradicating light scattering centes is presented.更多还原
