摘要

The present work illustrates the effect of the different heating rates on the intensity and peak area of thermoluminescence (TL) glow peaks. In this work, we suggest that the kinetic equations for the TL intensity in their time-dependent forms I (t) are not adequate for comparison with experimental results I (T), where the TL is recorded versus temperature. The present work suggests that in the case of TL experiments, the first-order kinetics equation, I (t) = -dn/dt = nS exp(-E/ kT), as well as the second- and general-order kinetics equation should be replaced by I (T) = -dn/dT = (nS/beta) exp(-E/kT), and a similar change should be made in the second- and general-order case. Also, the present work distinguishes between the decrease in the intensity and the stability of the area of TL glow peaks as a result of increasing heating rates and the decrease in both the intensity and area of TL glow peaks as a result of thermal quenching with increasing heating rates. The present work illustrates the effect of changing the heating rate on the characterization of experimental glow curves of BeO (thermalox) for different heating rates.
