Features of optically stimulated luminescence (OSL) during the 660 nm laser stimulation of nanoscale aluminium-nitride powders and impact of persistent phosphorescence decay at varying times of UV irradiation are studied. The necessity of accounting the phosphorescence for reliable and accurate estimation of absorbed dose by means of the OSL method is shown. As revealed after recording of the OSL response, intense signal of thermally stimulated luminescence (TL) is registered. It can be represented as a superposition of two peaks and used as an additional means for evaluating the absorbed dose of ionizing radiation. The values of kinetic microparameters for low- and high-tempera¬ture TL components, which are changing within the narrow limits by varying the exposure time, are calculated.
