Abstract
An organic-inorganic composite of the present invention includes metal oxide particles and an organic polymer compound including a monomer containing organic ligands and a vinyl-based monomer having organic ligands which are bonded to a polymer chain through covalent bonds and the organic polymer compound is bonded to the metal oxide particles by the organic ligands forming a complex with metal atoms on the surface of the metal oxide particles. According to the organic-inorganic composite, the metal oxide particles and the organic polymer compound containing the organic ligands can be chemically bonded, therefore, light emission characteristics such as light emission intensity or stabilization of light emission wavelength can be improved, and transparency and mechanical characteristics such as thermal stability or hardness can also be improved.
