Abstract
Deep trap population is an important parameter in studying thermoluminescence (TL) and phototransferred thermoluminescence (PTTL) processes. In this work a method is presented for estimating deep trap population and obtaining the probability of excitation of electrons from deep trap (gc) and active trap (gn) following UV irradiation. For doing so the rate equations of PTTL process considering one active trap, one deep trap and one recombination center were solved to obtain the PTTL signal curves. The above theoretical curves can be compared with the experimental data to estimate deep trap population and gc and gn parameters.
