Abstract: 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.

Key words: PbWO4 crystals, lattice defects, propertics of sciutillator
