Black phosphorus (BP) exhibits fascinating thickness dependent optical and electronic characteristics. However, photoluminescence (PL) emission in the visible spectrum does not exist for multilayer BP and requires the achievement of single layer, which are highly environmentally sensitive. This poses significant challenges in realizing the true potential of BP as multilayer BP exhibits exciting optical properties for a range of applications. Here, for the first time we reveal visible range room-temperature photoluminescence (PL) in multi-layered black phosphorus (BP) via chemical doping using organic molecules. We find the drastic enhancement of PL originates from the adsorption of p-type do..View full abstract
