The electron emission and luminescence which was associated with the plastic deformation of ionic crystals were studied. It was concluded that these phenomena could be attributed to the thermally activated intersections of edge dislocations which lay on oblique slip planes. Dislocation intersections of this kind were shown to result in color center generation, and recombination of the centers then gave rise to the deformation-induced electron emission and luminescence.
