Research Progress on Thermochromic Vanadium Dioxide Thin Film

The VO_2 thin film, which has excellent thermochromic properties, has been one of the most interes-ting functional materials. The thermochromic property is analysed combined with the crystal structure of VO_2. The preparation methods of VO_2 thin film, especially sputtering, chemical vapour deposition and sol-gel methods, are presented. VO_2 thin film has great prospects in many fields, and the potential applications in smart window, especially in the new fields; photon crystal, camouflage and stealthy technology, are viewed. Finally, the future study and de-velopment directions are pointed out.
