CGCD technique to find the kinetic parameters of TL glow curves


The behavior of ZnS:Mn,Cu,Cl phosphor by the effect of pressure was studied on the thermoluminescence (TL). Two prominent peaks were visible, increasing pressure the prominent peaks were also shifting to the higher temperature. Kinetic parameters of the glow curves were determined by computerized glow curve deconvolution (CGCD) technique. The order of kinetics (b) was found to be independent of pressure. All the peaks can be fitted with b=1.5. Computerised glow curve deconvolution (CGCG) method was used to determine the activation energy (E) order of kinetics (b) and frequency factor (s) of the different peaks present in the phosphor.
