Dual functionalities of antireflective and electrochromic properties-based anatase TiO(2) nanowire devices with a high-porosity cross-linked geometry directly grown onto transparent conductive glass was achieved for the first time through a simple one-step hydrothermal process under mild alkali conditions. Devices fashioned from these TiO(2) nanowires were found to display enhanced optical transparency in the visible range, better color contrast, and faster color-switching time in comparison to devices made from nanoparticles. These improvements can be attributed to the low refractive index and high porosity of the TiO(2) nanowires and their larger accessible surface area for Li(+) intercalation and deintercalation, leading to enhanced capabilities for transparent electrochromic smart windows.
首次通过在温和碱性条件下进行简单的一步水热工艺，在透明导电玻璃上直接生长具有高孔隙率交联结构的反反射和电致变色性能的锐钛矿 TiO(2) 纳米线器件实现了双重功能。与由纳米粒子制成的器件相比，由这些 TiO(2) 纳米线制成的器件在可见光范围内显示出更高的光学透明度、更好的颜色对比度和更快的颜色切换时间。这些改进可归因于 TiO(2) 纳米线的低折射率和高孔隙率及其更大的可用于 Li(+) 插层和去插层的表面积，从而增强了透明电致变色智能窗的能力。
