摘要
采用电子束及真空热蒸发的方式镀制了氧化钨薄膜及掺杂的氧化钨的复合共生薄膜。运用拉曼光谱以及电化学工作站等测试手段分析了氧化钨复合共生薄膜的结构及电致变色性能。通过对拉曼光谱曲线的解叠分峰处理发现,源于晶相的810cm-1拉曼峰的相对强度变化与样品的致色效率存在负相关,即拉曼峰相对强度越小,样品的致色效率越高。
Pure,TiO2-doped and TiO2/Ag-doped WO3 films were prepared by evaporation and electron beam evaporating.Raman spectroscopy and chronoamperometry were used to characterize the electrochromic properties of the samples.The correlation between the relative intensity of the Raman peaks,corresponding to the Raman sharp peak of the crystalline phase at 810 cm-1 is negative,that is to say the higher the relative intensity of the Raman peaks,the smaller the coloration efficiency.
