Paper Abstract

Two kinds of the electroluminescent cells containing CuxS-ZnS:Mn junction were investigated. In the first cells the CuxS layer was produced by wet chemical dipping method. In the second ones the layer was produced by thermal evaporation of the mixture of CuCl and ZnS. Both the cells exhibit characteristic yellow-orange manganese luminescence but luminescence intensity in the long wavelength side of the manganese band is greater for the second kind of the cells. This observation is in good agreement with our previous results, confirming existence of the structure of manganese band. Kinetic measurements show that luminescence lifetime of single as well as paired manganese centers are longer for the cells due to the second kind of the technological process. Also memory effect observed in current-voltage characteristics is larger for the cells.
