Abstract

Employing a barrier-cluster model, we attempt to explain qualitatively some experimental data on photoluminescence in non-crystalline semiconductors. We discuss the dependence of the photoluminescence intensity on the energy of quanta of the primary light irradiation in the exponential tail region of the optical absorption..
