【 摘 要 】

The results of the comparative analysis of the spectral and kinetic characteristics of the luminescence centers in the non-doped ZnWO4crystals and in crystals LiF doped with tungsten oxide. It was found that the intrinsic characteristics of the scintillation transition at 2.6-2.7 eV in these crystals do not depend on the energy and symmetry of the crystal lattice, have comparable values of the light output and can be attributed to the luminescence centers of the same impurity nature. The crystal lattice determines the efficiency of the creation and accumulation of radiation defects, presence of which leads to a distortion of the spectral and kinetic characteristics of scintillation.
