Promote doping efficiency and photoluminescence quantum yield of Mn-doped perovskite nanocrystals via two-step hot-injection

Manganese doped perovskite nanocrystals (NCs) have been synthesized by a novel two-step hot injection strategy with an unprecedented Mn doping efficiency of 48.5%, bright orange emission under ultraviolet light and X-ray excitation and a photoluminesce (PL) quantum yield of 84.4%, making them excellent luminescent materials.
