- Abstract
The role of defects formed owing to the deviations from stoichiometry is analyzed for CaWO4 single crystals grown by the Czochralski method. It is shown that the defects leading to the light scattering in CaWO4 crystals affect the spectra of X-ray luminescence and the luminescence kinetics only slightly, but give rise to an additional peak in the thermoluminescence spectrum. Addition of WO3 to the melt eliminates the light scattering and the additional thermoluminescence peak.
