Abstract
We propose a simple model for describing the electroluminescence in a single-layer thin-film organic electroluminescent cell on the assumption that the luminophore molecules are directly excited by electron impact and are the result of recombination. The calculated luminescence and efficiency curves are in qualitative and quantitative agreement with experimental data. To attain a high efficiency, it is necessary to use cathodes with a low work function and a high Fermi energy and relatively small electric fields.
