Physical origin of the anomalous temperature dependence of the $1 S$ yellow exciton luminescence intensity in ${Cu}_{2}$ O

Abstract

A simple model is presented to explain the minimum in the integrated intensity of the phonon-assisted $1 S$ yellow exciton luminescence in ${Cu}_{2}$ O as a function of temperature. It is shown that this behavior is due to a minimum in the temperature-dependent exciton population lifetime. This model also predicts the temperature dependence of the time-resolved luminescence spectrum in ${Cu}_{2}$ O.
