Notes:
A method is presented to analyze complex glow curves composed of several, possibly overlapping, peaks from thermally stimulated processes of general kinetic order and is applicable when the process studied is activated using any arbitrary temperature profile. A theoretical analysis is given to determine the properties of a single glow curve peak. Several new results are presented, among which is an expression for the peak temperature for general kinetic order and temperature profile. From the theoretical analysis of the asymmetry of a glow peak a method is described to determine the kinetic order of a peak and to obtain an initial estimate of the peak parameters sufficiently accurate to start a least-squares minimization procedure to determine the actual parameters of all peaks present in the total glow curve. The method is demonstrated for a synthetic glow curve and for two measured glow curves from a thermoluminescence experiment and a thermal gas desorption experiment.
