Luminescence Decay Kinetics of Electron-Hole Plasma in II-VI Epitaxial Layers and Micropowders

Abstract

The luminescence decay kinetics of epitaxial layers of ZnSe and micropowders of ZnSe and CdS were measured at room temperature and at high levels of optical excitation. Comparison of the experimental results with the theoretically calculated decay kinetics showed good agreement for the initial moment of time at high concentrations of nonequilibrium charge carriers.
