METHOD FOR PREPARING ORGANOMETALLIC PRECURSOR SOLUTION, ORGANOMETALLIC PRECURSOR SOLUTION PREPARED BY THE METHOD, AND METHOD FOR PRODUCING OXIDE SUPERCONDUCTING THIN FILM BY METALORGANIC DEPOSITION USING THE ORGANOMETALLIC PRECURSOR SOLUTION

摘要

Disclosed herein are a method for preparing an organometallic precursor solution, an organometallic precursor solution prepared by the method, and a method for producing an oxide superconducting thin film by metalorganic deposition using the organometallic precursor solution. The organometallic precursor solution is essential for the production of an oxide superconductor by metalorganic deposition. The organometallic precursor solution is applied to a substrate whose surface is textured (a ceramic single crystal substrate or a metal-ceramic composite substrate in which a textured ceramic thin film is formed on a metal substrate) to produce an oxide superconductor. According to the method for preparing the organometallic precursor solution, an organic solvent is used as a raw material other than trifluoroacetates, thereby enabling production of an oxide superconducting thin film with excellent superconductivity at reduced costs without being largely affected by the presence of moisture in air even during storage and processing, such as coating, in air.
