Abstract:

Room-temperature optically stimulated luminescence (OSL) response in UV-irradiated aluminum nitride (AlN) powders has been studied. Excitation of AlN powder by UV photons with energies within 3-5 eV gives rise to an intense afterglow that is related to isothermal quenching of recombination processes involving shallow donor centers. It is established that a useful OSL response separated on the background of this recombination afterglow represents a superposition of two components with decay kinetics order b = 1.0-1.2 and 1.7-2.1. Superlinear UV-dose dependences of the OSL light sum have been measured and the corresponding coefficients for each component have been analyzed in comparison to the available published data.
