Paper Abstract

Spectral and kinetic properties of the electroluminescent thin film cells containing ZnS:Mn and CuxS layers were investigated. The cells were produced by thermal evaporation and chemical dipping. Kinetic measurements indicate that, for high manganese concentration the decay curve can be expanded in two exponentials. These exponentials are due to two kinds of manganese centers. Mn2+ ions and Mn2+-Mn2+ pairs. For low cells exhibit a reach structure in the blue and green spectral regions. Further investigation disclosed the presence of two types of the spectra. We also obtained a structure of manganese band of the electroluminescence of the cells for high manganese concentration. Similar to the short-wavelength bands, there are two types of the manganese bands. To our knowledge, this is the first observation of such structure of manganese bands at room temperature.
