On the Possibility of using Commercial Software Packages for Thermoluminescence Glow Curve Deconvolution Analysis

V. Pagonis and G. Kitis

This paper explores the possibility of using commercial software for thermoluminescence glow curve deconvolution (GCD) analysis. The program PEAKFIT has been used to perform GCD analysis of complex glow curves of quartz and dosimetric materials. First-order TL peaks were represented successfully using the Weibull distribution function. Second-order and general-order TL peaks were represented accurately by using the Logistic asymmetric functions with varying symmetry parameters. Analytical expressions were derived for determining the energy E from the parameters of the Logistic asymmetric functions. The accuracy of these analytical expressions for E was tested for a wide variety of kinetic parameters and was found to be comparable to the commonly used expressions in the TL literature. The effectiveness of fit the analytical functions used here was tested using the figure of merit and was found to be comparable to the accuracy of recently published GCD expressions for first- and general-order kinetics.
