[PROBLEMS] To provide a novel resin composition having excellent transparency, light-absorbing / emitting ability and high refractive index, which can be used as a material for optical members such as optical waveguides, optical lenses and optical prisms. provide. SOLUTION: This composition is obtained by dispersing semiconductor ultrafine particles in a resin matrix, and the semiconductor ultrafine particles have a phosphorus atom-containing ligand copolymerized with a polymer chain constituting the resin matrix. Resin composition. |
