Activation Energies and Temperature Dependent Frequency Factors in Thermoluminescence Recorded with Hyperbolic Heating Scheme

Abstract

A method has been developed for the evaluation of activation energy of thermoluminescence peak recorded with hyperbolic heating scheme by taking into account temperature dependent frequency factor. We have arrived at a number of expressions of activation energy involving the peak temperature and/or temperatures corresponding to the two points of inflection of the peak. It has been observed that the temperature dependence of frequency factor might lead to an error of the order of 10% in the determination of activation energy.
