摘要: 采用溶胶_凝胶方法在ITO导电基底上制备氧化铑电致变色薄膜 .当在碱性溶液中对薄膜分别施加阴极和阳极电位时 ,薄膜即呈现由亮黄到深绿的可逆变化 .采用原位XRD、TG_DTA、IR、XPS等方法对薄膜的结晶态、热处理过程以及膜的化学组成进行分析 .应用交流阻抗法计算了薄膜变色过程的扩散系数 ,结果表明该膜基本可以用于变色器件

关键词: 电致变色, 溶胶_凝胶法

Abstract: Electrochromic rhodium oxide films were prepared on ITO substrate by sol_gel method. The films exhibited reversible two_color (bright yellow at reduction and dark green at oxidation) electrochromic behavior in alkaline solution with good cycle stability. In_situ XRD, TGA_DTA, IR, XPS methods were used for studying the structure and chemical process of the films. The diffusion coefficient during the electrochromic process was measured by electrochemical impedance spectra method. It was found that the rhodium oxide films may be suitable for the use in electrochromic devices.

Key words: Sol_gel method, Electrochromism, Rhodium oxide films
