There is disclosed a method for producing a metal oxide, which comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, and a metal alkoxide having an organic group with 6 or more carbon atoms) 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. According to that method, a metal oxide can be produced without applying a heat treatment at a high temperature of the degree adopted in the conventionally known application thermal decomposition method.

Method for producing a metal oxide and method for forming a minute pattern

A method of etching a surface of a transparent solid material with a laser beam, wherein the surface is irradiated with the laser beam having a fluence of 0.01-100 J/cm /pulse while maintaining a fluid capable of absorbing the laser beam in contact with an opposite surface of the solid material.

Method of etching transparent solid material with laser beam

There is disclosed a method for producing polymer articles having highly functionalized surfaces excellent in biocompatibility, by irradiating the surfaces of a polymer article with an ultraviolet laser beam in a solution containing a biopolymer. According to this method, a polymer article that has surfaces with biocompatibility, can be produced.

Method for producing polymer articles with a modified surface

There is disclosed a method for surface-modifying a fluorocarbonpolymer-molded article and a method for chemical plating the surface. The method for surface-modifying comprises irradiating the fluorocarbonpolymer-molded article with an ultraviolet laser beam having a wavelength of 250 nm or less, in the presence of hydrazine compound, to make a surface of the said fluorocarbonpolymer-molded article hydrophilic. The surface made being hydrophilic is made lipophilic by chemical treating with an organic acid anhydride. The method for chemical plating comprises chemical plating the surface made being hydrophilic by the above method for surface-modifying, to deposit a metal film on a surface of the fluorocarbonpolymer-molded article.
