METAL OXIDE NANOCRYSTALLINE FILM FIXATION SUBSTRATE, METAL OXIDE NANOCRYSTAL PRODUCTION METHOD, AND PRODUCTION METHOD FOR METAL OXIDE NANOCRYSTALLINE FILM FIXATION SUBSTRATE

摘要

This metal oxide nanocrystal production method is for producing metal oxide nanocrystals that contain a metal oxide formed of lead titanate or lead zirconium titanate, said method comprising a mixed solution formation step for forming a mixed solution by mixing: a lead acetate aqueous solution; a water-soluble titanium complex aqueous solution, or a water-soluble titanium complex aqueous solution and a water-soluble zirconium complex aqueous solution; and a quaternary ammonium compound. Said method further comprises a heating step for heating the mixed solution to synthesize metal oxide nanocrystals, and a separation step for separating the metal oxide nanocrystals from the residual liquid.
