Aluminum chloride assisted synthesis of near-unity emitting Mn2+-doped CsPbCl3 perovskite nanocrystals for bright white light-emitting diodes

Enhanced orange-red emitting Mn 2+ -doped CsPbCl 3 nanocrystals with a near-unity photoluminescence quantum yield of up to 98% are synthesized through an AlCl 3 -assisted hot-injection route.
