The general-semi analytical thermoluminescence (TL) expressions based on the one trap-one recombination center (OTOR) were developed to fit the single glow-peaks generated with exponential heating EHF) profile. The peak shape method (PSM) expressions based on the general-order kinetics (GOK) model were also developed for the glow-peaks generated with EHF profile. The success and failure of the GOK model in describing the glow-peaks generated with EHF was discussed. The new developed TL expressions were tested in the cases in which the other TL expressions based on the GOK model failed. The results showed that in the case of dose saturation and strong re-trapping probability, the error in the calculated activation energy (E) using the GOK model expressions exceeded 50%. While, using the new developed TL expressions, the error in the calculated E did not exceed 0.5%.
