Paper Abstract

The kinetics of thermoluminescence (TL) and isothermal phosphorescence decay is studied by means of the MOnte Carlo method.It was shown that non uniform distribution of traps may significantly change the shape of the luminescence curves measured. The phenomena are especially important in dosimetric applications of TL where a sample is exposed to a high-energy radiation, which produces large defects - traps and recombination centers, most probably assembled into groups. In some of these cases the classical models developed for the theoretical description of TL spectra are inappropriate. It was found that using standard methods of analyzing TL spectra one can identify 'false' peaks - attributing them to non-existing trap levels.
