本文介绍近年来钨酸铅晶体缺陷研究方面的进展，这些结果表明了在钨酸铅晶体闪烁性能研究中考虑晶体缺陷影响的重要性．根据钨酸铅晶体的特点，就闪烁性能与非化学计量配比、晶体结构／多型性、杂质效应以及氧组份等因素的关系进行了简略的讨论．
An introduction of recent progresses on the studies of lattice defects in lead tungstate crystals is presented. These results demonstrate the importance of taking into consideration in influence of lattice defects on performance of PWO scintillators. The relation among nonstoichiometry, crystal structure / polymorphism, impurity effects, oxygen composition and properties of scintillators is briefly discussed on peculiarities of PWO crystals.
