Abstract
AbstractLuminescence due to deformation is found in ionic crystals coloured at 77 and 193 K and the spectral characteristics of the process are investigated. It is shown that the deformation is accompanied by electron and hole capture by moving dislocations. Electron recombination with impurity ions and VK centres results in impurity and autolocalized exciton luminescence, respectively. Hole transfer by dislocations gives rise to a change of the F‐stimulated luminescence after deformation. New previously unknown luminescence bands occurring seems to be associated with exciton recombination in the dislocation field.
