Abstract

Many applications are based on the analysis of thermoluminescence (TL) glow curves. For these purposes, relatively simple but credible methods are required. In this paper a new fitting algorithm is presented for determination of the activation energy and other physical trap parameters from TL peaks. The fitting method was derived directly from the simple model. The algorithm allows the analysis of a single TL peak, as well as the deconvolution of complex TL curves. Using numerically generated TL spectra, preciseness and stability of the algorithm are studied. The results are compared with the classical fitting techniques based on the general order kinetics model. It is shown that the novel method is faster and in many cases gives more reliable results.
