V2O5 powder (99.5% purity) in H2O2 solution. The solution is spin-coated on glass substrates for optical (UV–VIS–NIR) and XRD analysis, and on ITOcoated glass substrates for electrochromic measurements. The samples are then annealed at 150°C for 1 hour. The resulting films have a yellow-orange color, typical of polycrystalline V2O5. XRD measurements have shown that after annealing in air at 400°C the structure of the films has a c-axis preferred orientation, the (0 0 1)-type planes lying parallel to the substrate. SEM analysis revealed a smooth surface. The films’ optical and physical constants (n, α, Eg, the thickness d and the mean thickness inhomogeneity s) are calculated using a simple and accurate method based on the transmission spectrum alone. The films’ electrochromism is studied using cyclic voltammetry (CV) and chronoamperometry in propylene carbonate solution containing 1 mol/l LiCIO4. The films show reversible multichromism (yellow–green–blue) upon Li+ ion insertion/extraction. The absorbance of films colored at three different potentials is measured in the UV–VIS–PIR wavelength range, and this study shows that the changes in the optical absorption are consistent with the film color changes. Finally, the optical and electrochromic properties of the films prepared by this method are compared with those of our sputtered films already studied and with other works."> 溶胶-凝胶V2O5 薄膜的结构、光学和电致变色性能 - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

摘要

采用溶胶-凝胶法制备了五氧化钒薄膜 V 2 O 5 粉末(纯度为99.5%) H 2 O 2 解决方案。该溶液被旋涂在玻璃基板上用于光学(UV-VIS-NIR)和XRD分析，并在ITOcoated玻璃基板上用于电致变色测量。样品在150℃下退火1小时。得到的薄膜呈橘黄色，是典型的多晶薄膜 V 2 O 5 ．XRD测试表明，在400°C的空气中退火后，薄膜的结构具有C轴取向，(0 0 1)型平面平行于衬底。SEM分析显示表面光滑。薄膜的光学常数和物理常数(n， α 例如，厚度d和平均厚度不均匀性s的计算采用了简单而准确的方法，仅基于透射谱。用循环伏安法和计时安培法研究了薄膜在1 mol/l碳酸丙烯酯溶液中的电致变色里西奥 4 ．薄膜表面呈可逆性多色(黄-绿-蓝) 李 + 离子嵌入/提取。测量了在UV-VIS-PIR波长范围内三种不同电位下着色的薄膜的吸光度，研究表明，光吸收的变化与薄膜颜色的变化是一致的。最后，将该方法制备的薄膜的光学和电致变色性能与已有研究的溅射薄膜进行了比较。
