This communication provides a brief summary on rare earth (RE)-based and RE free-based nitrides and oxynitride phosphors reporting for the first time the photoluminescence quantum yield (PLQY) of a highly emissive AlN:Mn2+ obtained at relatively low temperatures. The PLQY of the AlN:Mn emitter was measured to be 82%, a value among the highest measured for non-RE phosphors. Though the AlN matrix shows an emission peak at a similar position to the emission peak observed for AlN:Mn product, the Mn-containing species generates orange emission by a different mechanism, which was supported by the emission life time studies and in accordance with previous reports on this material.
