摘要
采用溶胶-凝胶法及浸渍提拉镀膜工艺,将钛酸四丁酯和冰醋酸加入溶剂无水乙醇中,并添加硼酸、去离子水、硝酸等原料,在ITO玻璃上成功制备了B^(3+)掺杂的TiO_2薄膜。采用TG-DTA、XRD、UV-Vis、SEM、电化学工作站等手段研究了B^(3+)掺杂TiO_2薄膜的光学属性及电致变色性能。结果表明,掺杂B^(3+)的TiO_2薄膜的光谱调控范围得到明显改善,薄膜的电化学循环稳定性得到提高,当B^(3+)掺杂体积分数为9%时,电致变色效果最佳。
Using sol-gel method and dipping coating process, tetrabutyl titanate and glacial acetic acid were added to the solvent absolute ethanol, and boric acid, deionized water, nitric acid and other raw materials were added. B3+ doped TiO2 film was successfully prepared on ITO glass. The optical properties and electrochromic properties of B3+ doped TiO2 films were studied by means of TG-DTA, XRD, UV-Vis, SEM, and electrochemical workstation. The results show that the spectral control range of B3+ doped TiO2 film was significantly improved, and as well as the electrochemical cycling stability of the film. When the volume fraction of B3+ was 9%, the electrochromic effect was the best.
