Selected results of Electron Spin Resonance study of various point defects, which participate in the processes of charge carriers transfer and capture in the family of practically important complex oxide single crystal scintillators based on tungstates, aluminum perovskites and yt-trium (lutetium) orthosilicates are presented. Particular attention is paid to the most natural defects inevitably present in oxide materials such as anion and cation va-cancies, antisite defects, self-trapped electron and hole states. Current understanding of the nature of such charge trapping states and mechanisms of their creation in the selected oxide scintillation materials is discussed as well.
