摘　　要：在云母衬底上采用溶胶-凝胶法制备了掺钨VO2薄膜,采用XRD、SEM、FT-IR和色差等检测手段,对掺杂薄膜物相、表面形貌、相变温度和热致变色性能进行分析。结果表明,掺钨后其相变温度降低到室温以下,并保持良好的红外透过率随温度变化性能;相变前后颜色发生了改变,色差最大值为5.9。W-doped vanadium dioxide films were fabricated on muscovite using inorganic sol-gel method.XRD,SEM,FTIR and color difference（ΔE＊）were used to analyze the microstructure,morphology,optical switching and color changing properties of the W-doped vanadium dioxide films.The results suggested that the phase transition temperature was decresed to room temperature and the films showed excellent optical switching property with the temperature as well.The color of films was changed,the maximum of color difference was 5.9 during the film metal-insulator transition.
