Abstract

A set of expressions are presented for the determination of activation energy of thermoluminescence peaks recorded with hyperbolic heating profile. Along with conventional half intensity points the peak widths at signal levels equal to 2/3 and 4/5 of peak height are used to determine the activation energy. A method of determination of order of kinetics of the peak by using its symmetry factor is also proposed. The present method is applied both to numerically computed and experimental TL peaks and encouraging results have been obtained.
