Abstract

The order of kinetics b of the thermoluminescence (TL) glow peak is usually determined once its symmetry factor is known. In the present work, an equation is suggested to estimate directly the order of kinetics b of the glow peak. The value of b can be obtained by using the values of the temperatures (K), (K) and (K) at the maximum intensity and half maximum intensities of the peaks, respectively and the peak areas , and estimated from , and to the final temperature of the glow peak, respectively. Also, the activation energy E (eV) can be obtained after evaluating the order of kinetics b. The methods were checked for numerically computed TL glow peaks. The results are in good agreement with the given values of the order of kinetics b and activation energy E.
