Theoretical and experimental investigation of the f(D)max-(S/S0)max anomaly in LiF:Mg,Ti.
Previous investigations in the framework of the Unified Interaction Model (UNIM) have demonstrated the difficulty in theoretically predicting both f(D)max and [S(Ds)/S(0)]max with the same set of UNIM parameters. This anomaly is re-investigated and an alternative explanation, based on experimental measurements combined with UNIM analysis, is given. This explanation is based on the assumption that N(LC), the total number of available luminescent centres is changed by the sensitisation dose or anneal or both. Allowing N(LC) to increase as the sensitisation dose is increased, a good fit to both f(D) and S(Ds)/S0 is obtained.
