Abstract
A method using a chemical synthesis method to produce a metallic nanoparticle inorganic composite having fine metallic nanoparticles that are uniformly dispersed at a high density in a solidified matrix, a metallic nanoparticle inorganic composite, and a plasmon waveguide using this composite are provided. Thus, a method including: preparing a precursor solution, applying the precursor solution onto a substrate, and then hydrolyzing the precursor solution to form an oxide film having fine pores, bringing the oxide film into contact with an acidic aqueous solution of tin chloride to chemically adsorb Snions in the fine pores, removing an excess of the Snions, bringing the oxide film into contact with an aqueous metal chelate solution to precipitate metallic nanoparticles in the fine pores, and removing an excess of ions of the metal is provided.
