    Abstract: A multicomponent light emitting nanoparticle, a luminophore containing the nanoparticle, and an organic photoelectric device containing the luminophore are provided to improve the energy transfer efficiency from a host to a dopant, thereby enhancing luminous effect. A multicomponent light emitting nanoparticle comprises a host compound which can transport a hole or an electron; and a dopant compound which comprises a coloring matter or a dye and is dispersed by a nano-size of 1,000 nm or less. Preferably the ratio of the host compound and the dopant compound is 0.1:1 to 10,000:1 by weight. Preferably the dopant compound is selected from the group consisting of an aromatic monocyclic compound, an aromatic fused ring compound, a hetero monocyclic compound, a hetero fused ring compound, a stilbene-based compound, a styryl-based compound, an azobenzene-based compound, a carbonium-based compound, an indigo-based compound, a squalene-based compound, fluorene and its derivatives, and their mixtures.
