Abstract
A method has been developed for the evaluation of activation energy of ther moluminescence peak recorded with hyperbolic heating scheme by taking into account temperature dependent frequency factor. We have arrived at. a numbe r 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 migh t lead to an error of the order of 10% in the determination of activation e nergy.
