Abstract
Lithium fluoride doped with Mg and Dy was fabricated for the first time using melting method. The optimum
concentrations of impurities and thermal treatment were studied to achieve high thermoluminescence (TL)
sensitivity. TL sensitivity of the fabricated phosphor is close to that of TLD-100 powder. Tm-Tstop technique was
used to identify the number of overlapped TL glow peaks. Initial rise, isothermal decay and computerized glow
curve deconvolution (CGCD) methods were applied to obtain kinetic parameters of the prepared TL material.
Three component glow peaks were distinguished at temperatures 395, 448 and 510 K. Other TL properties such
as fading, linearity of dose response and reusability are also presented and discussed.
