Abstract
The effect of states of bi- (Ca) and trivalent (Sb, Bi) impurities on the optical and scintillation characteristics of CsI crystals is studi ed. The variation of point defect states (quenching, deformation, impu rity concentration, diffusional activation) changes the correlation be tween different components of luminescence. The analysis of the obtain ed results leads to a conclusion about the role of cation vacancy type -defects for the localization of the exciton in CsI crystals.
