Abstract

A simple model for thin film organic electroluminescence in single layered one-dimensional cell with metal nanoparticles is developed, assuming direct excitation of luminophor molecules by electron impact. The values and behaviour of calculated curves for brightness and efficiencies correlate with experimental data. The insertion of metal nanoparticles into active volume of electroluminescent cell leads to the increase of the average electric field inside the cell and to the decrease of the threshold of electroluminescence and stimulated radiation due to improved conditions of electron tunneling as a result of potential barriers shape change..
