Use of peak widths for the determination of the trap parameters of thermoluminescence glow curves recorded with hyperbolic heating

Expressions are presented for the determination of the activation energy, the frequency factor and the order of kinetics for single thermoluminescence peaks recorded with hyperbolic heating. A 'general order of kinetics' equation of the form dn/dt=-const. n gamma exp(-E/kT) is assumed to apply. The peak widths at signal levels equal to 1 / 4 , 1 / 2 and 3 / 4 of the peak height are used for the determination of the energy and frequency factor, while the asymmetry of the peak gives the order of kinetics parameter gamma .
