The origin of a fast component of Mn 2+ 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.
