The influence of annealing in air at elevated temperatures on the absorption, luminescence andscintillation characteristics was studied for a set of Ce-doped aluminum garnet and perovskite singlecrystals. Positive effects consisting mainly in increase of light yield and decrease of afterglow were foundto varying extent in all the materials. It is explained by the positive role of created stable Ce4+ center in scintillation mechanism and by decrease of deep trap concentration based on oxygen vacancies.
