Abstract

The thermal quenching can be identified from diminishing of maximum temperature and peak intensity of thermoluminescence glow peaks by increase in heating rate. CaF2:Mn(TLD-400) is amongst the thermoluminescence phosphors that is affected by thermal quenching. thermoluminescence glow curve of this phosphor is contained 5 component glow peaks which obey first order kinetics. Using the given thermal quenching parameters of this phosphor, the kinetic parameters of all component glow peaks were evaluated with and without considering thermal quenching effect based on first order kinetics. This was carried out by fitting the experimental glow curve with theoretical models for different heating rates. Considering that the function describing the thermoluminescence intensity in presence of thermal quenching differs from that in absence of thermal quenching, fitting procedure results different kinetic parameters for two above cases.
