Abstract
Glow curve shape and thermoluminescence (TL) sensitivity in LiF:Mg,Ti single crystals have been studied as a function of Mg2+ and Ti3+ concentrations. A detailed method for TL optimization is presented, along with a simplified scheme which relies on the ratio of peak 5 height to peak 4 height (or ratio of peak 5 to peak 3) and the height of peak 3. In addition, the role of hydroxyl (OH−) impurities has been investigated and it has been found that some Mg ions are removed from the TL process by forming magnesium-hydroxyl complexes Mg(OH)n. This may explain prior discrepancies in Mg and Ti concentrations for optimum TL sensitivity.
