Ligand density control boosts the efficiency of all-inorganic CsPbBr3 perovskite nanocrystal based light emitting diodes

Lead halide perovskites attracted a lot of attention in the last several years,with a focus gradually shifting from the record power conversion efficiencies reported for photovoltaic devices based on thin perovskite films[1]towards superior

Lead halide perovskites attracted a lot of attention in the last several years, with a focus gradually shifting from the record power conversion efficiencies reported for photovoltaic devices based on thin perovskite films towards superior luminescence properties of the colloidal perovskite nanocrystals （NCs）.
