Abstract
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 V 3‐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.
