Thermoluminescence kinetic parameters of basaltic rock samples due to continuous trap distribution

The thermoluminescence (TL) of natural materials usually exhibits a complex behaviour, which in most cases cannot be explained in terms of localised trapping states. In this paper, the kinetic parameters of the trapping states distribution of a polymineral sample have been estimated to confirm the presence of an exponential trap distribution. These TL behaviours could engage the consecutive breaking and linking of bonds Al–O, Fe–O, including dehydroxylation processes and redox reactions.
