The present invention refers to a near infrared of emitting light in the ultraviolet region Er, Nd, Tb, ZnO nano-particle such as Eu photoluminescent ions are such that with low volume state of or containing solution at temperatures relevant for easy coating film formation by coating alkyl silica and zirconia sol such as an optically functional is configured of nanocomposite/organic free relates to in-situ manufacturing method, more particularly alkyl silane monomer and a silane compound photoactive in a medium, which is present and zirconia and process ion form coordinates to inorganic oxide film formed by in-situ of nanoparticles the, said photoactive of ions homogeneous dispersion and inorganic oxide coordinates to the photoactive ion between is thereof lumping which is higher efficiency light emitting nanoparticles coupled by silane alkyl around and superior dispersibility even organic, micro 5 coating once m or more crack-free coating film formation capable composite and its organic nanoparticle/radish relates to manufacturing method.
