The results of experimental measurements and computer simulations on optically stimulated luminescence (OSL) from a-Al2O3:C are described. The intensity of OSL observed during illumination of irradiated specimens with visible light is temperature dependent. Optical stimulation is observed from the main dosimetric traps, and from deep traps. The temperature dependence appears to be due to the presence of shallow traps, with a possible additional contribution from thermally assisted optical excitation.
