| Popis: | Kinetic simulations of the thermoluminescence characteristics of LiF:Mg, Ti are reviewed in the framework of conduction band/valence band models. Delocalised recombination models have been mainly applied to the simulation of glow peak shapes, although comparison with experimental data has proven difficult if not impossible due to the scarcity of materials with demonstrably proven ‘single-peak’ glow curves. The delocalised models are incapable of the simulation of TL dose response linear/supralinear behaviour and the dependence of the supralinearity on particle energy. These characteristics require the incorporation of localised, nanodosimetric, recombination processes in the TL mechanisms. These investigations have simulated many of the TL characteristics of LiF:Mg, Ti in kinetic models based on a mixture of both delocalised and localised recombination. |
