The high-temperature dosimetry glow peaks in LiF: Mg are thought to result from thermal release of electrons from traps associated with the Mg impurity. There is also evidence, however, that the visible-light emission in the same glow peaks is due to recombination of mobile holes. These observations were reconciled by a mechanism proposed by Mayhugh in which the thermally ionized electron frees a V3-center hole, which then emits a photon at another recombination center. We find that this model is supported by new measurements of Podgoršak, Moran, and Cameron on glow peaks which occur below room temperature.
