Abstract

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.
