LUMINESCENCE FROM PLASTICALLY BENT CRYSTALS OF CADMIUM SULFIDE

Abstract
Plastically bent crystals of CdS exhibit different luminescent spectra at 77°K depending on the type of edge dislocations. The bending of the crystals around an axis in a [01̄10] direction permits selective introduction of either Cd or S dislocations after completion of polygonization in conformity to the sense of the bending. The crystals with S dislocations showed two emission bands at about 6350 Å and 7400 Å of much more brightness than those with Cd dislocations.
