Abstract

The invention provides an inorganic all-solid state electrochromism component and the preparation method thereof. The component has the structure that a tungsten oxide film, a compound film of lithium metaborate and lithium sulfate, a nickel oxide film and an indium tin oxide film are deposited in turn on a tin doped indium oxide glass substrate. The preparation method has the following steps: tin doped indium oxide conductive glass is incised into substrates, the size of which is suitable to that of an instrument and equipment, and the substrates are ultrasonic washed in turn in acetone, anhydrous alcohol and demineralized water; the sputter foil cavity of a multi-target magnetic control sputtering apparatus which is loaded with the substrates is vacuumized to 1*10<-4> Pa; then the tungsten oxide film, the compound film of lithium metaborate and lithium sulfate, the nickel oxide film and the indium tin oxide film are deposited in turn. The invention has great value in the research and the application of dichroic glass, an antidazzle viewfinder, an information display screen and an energy conservation promoting window according as the electrochromism component prepared by the method of the invention has the performance of changing the transmittivity of visible light, and has the characteristics of wide modulation range and short action time.

Description

(1) Technical field: [0001] The invention relates to an inorganic all-solid-state electrochromic element and its preparation method, in particular to preparing an electrochromic multilayer film on a transparent conductive glass. The multilayer film forms an electrochromic element, and the element can be realized by applying a voltage. The invention relates to the transition between blue and transparent; it belongs to the technical field of preparing electrochromic multilayer thin films on transparent conductive glass. (two) background technology: [0002] Electrochromic (EC) materials can adjust light absorption and transmission under the action of an electric field, and can selectively absorb or reflect external heat radiation and prevent internal heat diffusion, reducing the cost of office buildings and residential buildings, etc. A large amount of energy must be expended to keep buildings cool in summer and warm in winter. At the same time, it also plays the role of impr...

AI Technical Summary

Problems solved by technology

At present, most of the first two EC components are used, but because the liquid electrolyte and the organic polymer electrolyte have a certain corrosion effect on the adjacent electrochromic materials and ion storage materials, and the ions are easy to diffuse, so its Lifespan and coloration stability are not ideal

The EC element with full-thin film structure has superior performance in terms of service life and coloring stability, but the preparation conditions of this electrochromic element are very demanding. Currently, electron beam evaporation, sputtering, and thermal evaporation are mostly used in foreign reports. , pulsed laser deposition and other methods for multi-layer film preparation, and the ion-conducting material mostly uses expensive lithium niobate (LiNbO 3 ), lithium tantalate (LiTaO 3 ) and other materials, while domestic research on EC components with a full-thin film structure is still relatively small
