Numerical analysis of the irradiation and heating processes of thermoluminescent materials

Abstract

The deconvolution of thermoluminescence (TL) glow curves into a sum of individual peaks described by First Order Kinetic (FOK) equations, implies that retrapping probability should be negligible compared with re combination during the readout (to avoid non-linearity) but not during irradiation (to allow the filling of the traps with the produced electron-hole pairs). In this contribution, some examples of TL glow curves simulated using a general model are discussed to show that FOK shape and deconvolution into individual glow peaks fitted by FOK equations is compatible with a non-negligible traps filling process during irradiation with the appro priate choice of kinetic parameters and probability factors
