Photostimulated Thermoluminescence in KBr Single Crystals

抄録

KBr single crystals are investigated by means of photostimulated thermoluminescence from 50 to 250°K. The spectral range of photostimulation is 240–700mμ. No evidence of V band stimulation has been found; only electron traps are involved in the stimulation process. Filling of the traps occurs either through capture of photoelectrons from the conduction band, or by tunneling of electrons from excited F centers to neighbouring traps.
