Journal of Applied Spectroscopy Aims and scope

Abstract

This paper analyzes the possibilities of obtaining induced radiation in single‐layer organic electroluminescent structures on the basis of the proposed model of luminophor molecule excitation by “hot” electrons emitted from the cathode as a result of the tunnel effect. Numerical calculations of the kinetic, spectral, and energy characteristics of radiation in the regime of single‐pass superluminescence and in the presence of positive feedback have been made. It has been concluded that, in principle, it is possible to obtain in such systems induced radiation at actually attainable values of the applied electric‐field strength, and the conditions for this have been analyzed.
