METHOD FOR PRODUCING COMPLEX METAL OXIDE MICROPARTICLE-CONTAINING RESIN MATERIAL AND OPTICAL ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a complex metal oxide microparticle-containing resin material having low moisture absorption and high transparency while enabling control of the refractive index in a range which is suitable as an optical element by adding metal oxide microparticles to a resin material and to provide an optical element by using the resin material.

SOLUTION: The method for producing the complex metal oxide microparticle-containing resin material comprises a step for synthesizing complex metal oxide microparticles by using a solution containing at least 2 kinds of metal elements while adopting a supercritical state or a subcritical state as a reaction field and carrying out surface modification of the complex metal oxide microparticles and a step for mixing the complex metal oxide microparticles with a curable resin or a thermoplastic resin.
