The thermoluminescence spectra and glow curves of MeF 2 : Y, MeF 2 : Tm (Me:Ca, Sr, Ba), and CaF 2 : Sm single crystals are measured over the temperature region from 89 to 300 °K and compared with earlier results obtained above room temperature. It is established that temperature has a considerable effect on the spectral intensity distribution of the thermoluminescence emission and effects are observed which arise from both the activator concentration and a charge compensation by NaF. A brief discussion is given of the results.
