Bulk single crystals were deformed in uniaxial compression and were studied by using photoluminescence and cathodoluminescence techniques. The deformed samples exhibited a photoluminescence emission band which peaked at 603nm. Its intensity increased with increasing plastic deformation. The band was related to the density of dislocations which was produced during the interaction of slip systems. This hypothesis was supported by cathodoluminescence images which revealed the activation of successive slip systems that corresponded to various levels of deformation.
