我们报告了采用掠射角沉积（GLAD）技术制备的沉积态和退火纳米结构三氧化钼薄膜的电致变色响应。用原子力显微镜 (AFM) 获得的沉积薄膜的形貌显示，典型的晶粒尺寸为 10 至 50 nm 直径。退火后，AFM 图像清楚地显示出层状结构的主要存在，这是三氧化钼的斜方 (a) 相的特征，典型晶粒尺寸为几微米。退火样品在电磁波谱的可见光和近红外区域显示出明显的着色，而沉积样品仅在可见光区域显示出明显的着色。
We report on the electrochromic response of as-deposited and annealed nanostructured molybdenum trioxide films prepared with the glancing angle deposition (GLAD) technique. Morphology of the as-deposited films, obtained with an atomic force microscope (AFM), showed a typical grain size of 10 to 50 nm diameter. After annealing, the AFM images clearly showed the dominant presence of a layered structure, characteristic of the orthorhombic (a) phase of molybdenum trioxide, with typical grain dimensions of a few micrometers. The annealed samples showed pronounced coloration in the visible and near-infrared regions of the electromagnetic spectrum, while the as-deposited samples showed significant coloration only in the visible region.
