Abstract

This paper presents the results of a study of deep traps responsible for thermally stimulated luminescence in single crystals of the anion-defective corundum α-Al2O3: C observed at temperatures of about 703, 778, 830, and 903 K. The effect of the filling of these traps by carriers of both signs on the sensitivity to radiation of the main thermoluminescence peak at 450 K, optically stimulated luminescence, and phototransferred thermoluminescence has been investigated. The results obtained are treated in terms of a model involving interactive competition of traps of different depth.
