Abstract

The electroluminescent thin film cells based on ZnS:Mn were investigated. The ZnS:Mn and Al electrodes were produced by thermal evaporation and the Cu_xS layer was formed by a wet chemical process. The cells were excited by short rectangular voltage pulses of 10 microsecond(s) . The electroluminescence of the cells exhibited two exponential kinetic components with a long lifetime (tau) _s equals 333 microsecond(s) and a short lifetime (tau) _o equals 98 microsecond(s) . The maximum of the electroluminescence appeared after the end of the exciting pulse. Also nontypical behavior of the luminescence during the exciting pulse was observed. In order to explain the phenomena the energy transfer between monomolecular centers was assumed. It is shown that the relations based on the assumption fit well the experimental data for copper as the transferring and manganese as the emitting center.
