Investigation of the Duration and the Decay Law of Cathodoluminescence and their Relation to the Position and Occupation of Localization Sites of Electrons and Holes

Abstract

The luminescence decay is determined by the kinetics of the de-excitation process and therefore it gives important information about its nature. In the simplest cases it leads to a unique conclusion. Thus the de-excitation of a system of discrete centers gives an exponential decay, while a simple recombination process results in a second-order hyperbolic decay.
