Abstract

In present work we analyze the suitability and feasibility of analysis method, developed on mechanism proposed by Prakash, for the determination of T L decay parameters, namely the activation energy or trap depth, frequency factor and order of kinetics or extent of retrapping, of a thermoluminescence (TL) spectrum by applying it to both experimentally reported TL spectrums or glow curves of specimens Natural Biotite [K(Mg, Fe)3AlSi3O10(F, OH)2], a mineral within the mica group, and Copper doped ZnS and to a TL glow curve of hypothetical system. It is found that the method is simpler, convenient and can be used for glow curves of any order of kinetics or any extent of retrapping.
