摘要：

A model describing the luminescence mechanism of anion-defective single crystals of aluminum oxide was developed including thermal ionization of excited states of F-centers. The model was validated by experimental studies on the effect of deep traps on specific features of thermoluminescence, thermally stimulated exoelectron emission, and thermally stimulated electric conductivity of test crystals.
