Abstract:

The ac electroluminescence EL of Cu-doped ZnS single crystals is reported. Several aspects of a thermally induced aging effect are briefly described, which include evolution with the thermal treatment of the light-voltage relationship parameters, hardness increase, dislocations decoration, and optical microscope evidence of the conversion of the EL patterns from hairlike to comet -shaped form. Pictures are also shown, that give information as to the phase relationship of the light emitted from different specimen areas. The qualitative implications of these results as to the current theories are discussed, particularly their inconsistency with the mechanism of impact ionization. Author
