An improved mixed order model for describing thermoluminescence glow curves

An improved mixed order model is presented to describe the thermolumunescence (TL) glow peaks. In this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. Therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. The TL glow curves generated by the proposed model are fitted to the glow curves of general order and mixed order models using a curve fitting program. The results are presented and discussed.
