Abstract

The stresses existing in glasses cause a definite orientation and possibly some deformation of the luminescence centres created by the activators in glass. This orientation of luminescence centres cause a polarization of the light emitted by these centres. The distributions of polarization degree for luminescence were measured along the determined directions in rectangular cubes of glass. It has been pointed out that the stress distribution in glass is correlated with the polarization degree of the luminescence.
