Optically stimulated luminescence in strongly irradiated anion-deficient corundum and associated phototransfer effects

Optically stimulated luminescence (OSL), its mechanisms and the role of phototransfer effects in it have been comprehensively studied for strongly irradiated anion-deficient corundum with a high-temperature thermoluminescence (TL) peak at 830 K and without it. The fast component of the OSL kinetics in the samples was found to be due to the emptying of the main trap. The slow component was observed only in samples with the 830 K TL peak and was caused by the depletion of deep traps responsible for TL peaks in the range of 500 K<T<740 K. © Published under licence by IOP Publishing Ltd
