Title: A High Efficiency Rare Earth-Free Orange Emitting Phosphor

This work reports the synthesis at relatively low temperatures of a highly emissive AlN:Mn2+ emitter. 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 red emission by a different mechanism, which was supported by the emission life time studies. The PLQY of the AlN:Mn emitter was measured to be 82%, the highest ever reported on a RE free-based phosphor.
