以钛酸四丁酯和硝酸钐为主要原料,采用溶胶-凝胶法制备了 Sm 掺杂 TiO2薄膜。Sm 掺杂的摩尔分数分别为0,2%,5%,10%和20%。采用XRD和TG-DTA表征了薄膜的结构和热重特性,使用电化学工作站和紫外-可见分光光度计研究了薄膜的电致变色性能。结果表明,Sm掺杂使得 TiO2薄膜具有更高的无定形程度。250℃热处理的 Sm 掺杂 TiO2薄膜具有较高的电荷存储能力和循环可逆性。Sm 掺杂量为5%时,薄膜的峰值电流最大,电荷存储能力最强,注入电荷密度为13.35 mC/cm2,循环可逆性 K 值为0.92。Sm掺杂 TiO2薄膜在可见光范围内具有较好的光学透明度,透光率在70%~80%。适于用作电致变色器件的离子存储层。

Sm doped TiO2 thin films were prepared by sol-gel methods with butyltitanate and samarium nitrate as main components.The Sm doping molar ratios are 0,2%,5%,10% and 20%.Structural,thermogravimet-ric and electrochemical properties were investigated by XRD,TG-DTA,cyclic voltammetry curves(CV)and ul-traviolet visible spectroscopy.The result indicates that the Sm doped TiO2 thin film has higher amorphous de-gree.When the heat processing temperature was at 250 ℃,Sm doped TiO2 thin film has good ion storage ca-pacity and cyclic reversibility.When the doped amount of Sm was at 5%,the peak current of thin film reaches its maximum value with most powerful charge storage capability,injected charge density at 13.35 mC/cm2 ,and cyclic reversibility K value at 0.92.Sm doped TiO2 thin film has good transparency in the visible light range and transmittance was 70%-80%.This would be used as ion storage material in electrochromic glass.
