Abstract: The present disclosure relates to a illuminant comprising an inorganic luminescent particle having at least one metal component on a surface thereof, and an (iso) quinoline-based ligand coordinated to the at least one metal component, a light-emitting diode and a light-emitting device including the illuminant in an emitting material layer (EML). The illuminant enables white luminescence in the light-emitting diode with only single emissive unit.
