Claim Text:
1. A method for preparation of an organic-inorganic hybrid composition, comprising performing hydrolysis reactions and condensation reactions with a functional organosilane or a combination of functional organosilanes, in presence of water as a reactant for hydrolysis and a suitable acid or base as a catalyst, wherein said step of performing hydrolysis reactions and condensation reactions further comprising adding a metal doping agent, wherein said metal doping agent being one or more selected from the group consisting of metal alkoxides, metal halides, titanium acetate, zirconium acetate, titanium propionate, zirconium propionate, and potassium titanium oxalate; obtaining a first intermediate, wherein the first intermediate comprises a plurality of hydroxyl groups, and the plurality of hydroxyl groups are selected from the group consisting of Si—OH, Ti—OH, Zr—OH and combinations thereof; preparing a hydroxyl group-capping intermediate; performing a hydroxyl group-capping reaction with the first intermediate and the hydroxyl group-capping intermediate; irradiating with an ultraviolet (UV) light or an electron-beam; polymerizing to form an organic-inorganic hybrid polymer composition; obtaining said organic-inorganic hybrid composition; and an atom ratio of metal atoms in said metal doping agent over silicon atoms in said functional organosilane or said combination of functional organosilanes being 1.0 :19.0 to 19.0:1.0.
