Spin Selection Rules in Radiative and Nonradiative Recombination Processes in Bulk Crystals and in Thin Films of II-VI Compounds

Abstract

The origin of a fast component of Mn2+ intra-shell photoluminescence (PL) decay is discussed. We demonstrate that efficient spin-dependent interactions between localised spins of Mn ions and spins of free carriers result in a variation of formation and decay rates of PL emissions in diluted magnetic semiconductors and affect spin selection rules for radiative recombination transitions.
