Thermoluminescence glow curve deconvolution for discrete and continuous trap distributions

Highlights: • New software for thermoluminescence glow curve deconvolution has been developped. • Accurate algebraic equations for first order and general order kinetics have been obtained. • New equation for a continuous trap distribution has been obtained. • Both discrete and continuous trap equations, the considered parameters can be estimated from the glow curve analysis. • Results with simulated glow curve is presented and discussed. - Abstract: Deconvolution analysis of the thermoluminiscent (TL) glow curves proved to be a good complementary method to characterize the individual glow peaks by fitting their kinetic parameters. In this work, new software has been developed for the automatic deconvolution of TL glow curves, assuming either discrete or continuous distribution of trapping centres. The guess estimation of the kinetic parameters is done automatically and can be manually modified, thus allowing the use of the software for routine, processing a large number of measurements, as well as for research purposes. The equations, the methods and the results of the first test are described in detail. The software has been developed by integrating Fortran code and Visual Studio tools to create a graphic easy-to-use environment and permits to obtain the fitted values for the parameters according to the considered model.
