Thermoluminescence glow-curve deconvolution (GCD) functions are proposed for first, second and general orders of kinetics. The free parameters of the GCD functions are the maximum peak intensity and the maximum peak temperature , which can be obtained experimentally. The activation energy (E) and the order of kinetics (b) in the case of general order kinetics are the additional free parameters.
Thirteen different computer programs for glow curve analysis are compared. Eleven programmes used a shape of the glow peak based on the Randall-Wilkins model, but a variety of different approximations for evaluating the peak shape was noticed. Twelve programmes were able to reproduce the peak areas and activation energies of a synthetic glow curve according to the Randall-Wilkins model simulating a four peaks TLD-100 glow curve within 6.3%. Four programmes of those twelve were able to reproduce the input values within 0.4%. Clear differences in performance between the programmes are due to differences in approximations used in calculating the glow peak shape.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
