초록 ▼

The present invention provides a reflective control switchable thin film material that can become completely colorless when transparent, and the present invention relates to a reflective control switchable thin film material composed of a multilayer thin film in which a magnesium-titanium alloy thin film is used, and to reflective light control glass, and light control window glass, wherein a magnesium-titanium alloy thin film is used as a control switchable layer, a catalyst layer is formed on the surface of the thin film, a protective layer is optionally formed over the catalyst layer, the material has chromic characteristics whereby a colorless and transparent state is produced by hydrogenation at room temperature (about 20�� C.), and the material has chromic characteristics whereby a mirror state is produced by dehydrogenation at room temperature (about 20�� C.), and thereby a novel magnesium-titanium alloy thin film material that exhibits excellent reflective control switchable characteristics and is colorless when transparent is provided.

What is claimed is: 1. A reflective control switchable thin film material composed of a multilayer thin film in which a magnesium-titanium alloy thin film is used, comprising (1) a magnesium-titanium alloy thin film used as a control switchable layer, (2) a catalyst layer formed on the surface of said thin film, (3) a protective layer optionally formed over said catalyst layer, the material (4) has chromic characteristics whereby a colorless and transparent state is produced by hydrogenation at room temperature of about 20�� C., and (5) has chromic characteristics whereby a mirror state is produced by dehydrogenation at room temperature of about 20�� C. 2. The material according to claim 1, wherein the magnesium-titanium alloy thin film has a composition of MgTix, wherein 0.1x 0.4, and contains crystallized magnesium. 3. The material according to claim 1, wherein the thickness of the magnesium-titanium alloy thin film is 10 to 200 nm. 4. The material according to claim 1, wherein the control switchable layer becomes colorless during hydrogenation, and chromaticity coordinates calculated from the transmission spectrum of said layer are within a distance of 0.02 from the point x=0.333 and y=0.333. 5. The material according to claim 1, wherein the surface of the thin film is coated with 1 to 10 nm of palladium or palladium alloy as a catalyst layer. 6. The material according to claim 1, wherein the protective layer is composed of a material that is transmissive to hydrogen and non-transmissive to water. 7. A reflective control switchable member, comprising a light control component composed of the reflective control switchable thin film material using a magnesium-titanium alloy thin film defined in any one of claims 1 to 6, formed on the surface of a transparent member. 8. The reflective control switchable member according to claim 7, wherein the light control component is formed on a glass surface. 9. A gas chromic reflective light control glass window composed of multi-ply glass, comprising the reflective control switchable member according to claim 8 used on one side of the multi-ply glass. 10. The gas chromic reflective light control glass window according to claim 9, wherein an atmosphere controller that introduces hydrogen gas, air, or oxygen gas is provided in a gap of the multi-ply glass. 11. An electrochromic reflective control switchable material, comprising a structure in which electrolyte is sandwiched between a transparent electrode and the reflective control switchable thin film material using a magnesium-titanium alloy thin film defined in any one of claims 1 to 6. 12. An electrochromic reflective light control glass window, comprising the electrochromic reflective control switchable material defined in claim 11 applied to a glass window.
