Abstract The thermoluminescence of plastically deformed KBr crystals is measured in the temparature range 80‐350 °K for differing amounts of deformation. It is found that the glow peaks characteristic of undeformed crystals are greatly enhanced but that no new glow peaks appear. The effect of annealing at different temperatures, before X‐ray excitation shows that the enhanced emission is not due to direct trapping of carriers by dislocations. The study of changes in the absorption spectra indicates that there is no correlation between coloration and enhanced emission of different deformed samples.
