Participation of shallow and deep traps in the processes of energy transfer and capture is studied by means of timeresolved emission spectroscopy and thermoluminescence in several groups of the Ce3+ and Pr3+ -doped complex oxide single crystal scintillators. Tunnelling-driven recombination processes are distinguished in all the groups of examined materials: closely spaced electron and hole traps give rise to the t -1 phosphorescence decays at low temperatures in the Ce-doped aluminum garnets and perovskites, while thermally assisted tunneling process is proposed to explain temperature Independent trap depth in glow curve peaks within 50-250°C in Ce-doped lutetium orthosilicates.
