Abstract

The thermoluminescence (TL) glow peaks of nanoparticles was simulated by a the Monte Carlo method in which all the ordinary as well as anomalous transitions between the nanoparticle clusters are taken into account. The adjustable parameters are activation energy and frequency factor of the trap, both   radiative and nonradiative recombination, direct recombination from trap to recombination center and two extra parameters introducing electron transitions between the clusters. The obtained results were fitted to the experimental  TL glow peak of the LiF:Mg,Cu,P nanoparticles and good consistency was observed between the simulation and the experiment.
