Emission of light is found during application as well as release of uniaxial pressure in X‐ray irradiated alkali halide crystals. As unpinning of dislocations can not take place, however, dislocations can move in backward directions during release of the pressure; the emission of light during release of pressure gives a direct support that the interaction of moving dislocations with F‐centers is responsible for the emission of light during deformation of colored alkali halide crystals.
