Abstract: L ithium Auoride (LiF) thermolum inescent powder doped with Mg, Cu, Na, and Si as activators was prepared. X-ray diffraction analysis indicated that doping LiF vvith different activators m akes crystal lattice som ew hat expand. The dosimetric properties o f the powder were studied. The main dosimetric peak of LiF:Mg,Cu,Na,Si appeared in the range of 227 - 247°C and the ratio of the height of the main peak to that of the other small peaks in the LiF:Mg,Cu,Na,Si is much greater than that in the LiF:Mg,Ti and LiF:Mg,Cu,P. The preparation conditions such as annealing temperature and duration, annealing atmosphere, doping vvith different activators etc. were investigated.
