The validity of the two heating rates method to obtain the trapping parameters from general-order thermoluminescence glow peaks
چکیده انگلیسی
The two heating rates method, which is usually known as Booth-Bohun method, is currently employed for obtaining the activation energy E (eV) of first-order thermoluminescence (TL) glow peak. However, this method can be used for obtaining the activation energy for all types of TL glow peaks irrespective of their order of kinetics (b). The present work shows that the condition of maximum intensity of first-order kinetics can be safely used to obtain the pre-exponential factor S″ (s−1) in the case of general-order glow peak when Booth-Bohun method was used to obtain E. Also, the present work suggests a numerical method for obtaining the order of kinetic (b) of general-order glow peak. This method depends on the activation energy E obtained by Booth-Bohun method and the suggested method mentioned above to obtain S″. An independent evaluation of the suggested methods is illustrated here by taken some numerically computed glow peaks by applying the one-trap and one-recombination-center (OTOR) model.
