Radiative recombination processes in β-ZnP2 single crystals

Abstract

The exciton states in monoclinic β-ZnP2 crystals was the subject of many research papers over a long period of time and have been extensively examined. In this work is reported that besides the excitonic luminescence in these crystals there is a broad band emission caused by the recombination via an intrinsic defect. This emission acts as a competitive channel for the excitonic radiative recombination.
