On some fundamental features of optically stimulated luminescence measurements

The influence of electron–phonon interaction on the shape of the optically stimulated luminescence decay curve has been examined. The formula describing the dependence of optical cross-section on stimulation energy and temperature has been applied in a computer simulation of optically stimulated luminescence process. Computer simulations have been carried out for different temperatures using both one-trap and two-trap models. The ideas of an OSL measurement with continuously increasing energy of stimulation have been tested via computer simulations. The outcomes of this technique have been presented for a wide range of material parameters.
