Abstract:
A method for producing a metal oxide, comprising the steps of:dissolving a metal organic compound in a solvent to provide a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or less wavelength, to form a metal oxide on the substrate, wherein the laser light irradiation of a 400 nm or less wavelength is carried out in a plurality of steps comprising a first irradiation step carried out with a weak irradiation to a degree that does not completely decompose the metal organic compound, followed by an irradiation step carried out with a strong irradiation that changes the metal organic compound to an oxide, provided that the metal organic compound is not a metal alkoxide having an organic group with 5 or less carbon atoms.
