Abstract

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 is significantly improved, The electrochemical cycling stability of the film is also improved. When the volume fraction of B³⁺ is 9%, the electrochromic effect is best.

摘要

采用溶胶-凝胶法和浸涂工艺，在溶剂无水乙醇和硼酸、去离子水、硝酸等原料中加入钛酸四丁酯和冰醋酸。在ITO玻璃上成功制备了B ³⁺掺杂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薄膜的光学性能和电致变色性能。结果表明，B ³⁺掺杂TiO ₂薄膜的光谱控制范围显着提高，薄膜的电化学循环稳定性也有所提高。当 B ^{3+的体积分数}为9%，电致变色效果最好。
