摘要(Abstract)：

在150℃条件下,以钛酸丁酯为钛源,盐酸和蒸馏水为溶剂,采用水热法通过改变水热反应时间、Ti(OC_4H_9)_4浓度、盐酸和水的比例,在掺F-SnO_2玻璃基板上制备TiO_2薄膜。通过X射线衍射仪(XRD)、扫描电镜(SEM)、紫外可见分光光度计(UVVis)等对样品的形貌结构进行表征。结果表明:TiO_2薄膜由均匀排列的金红石相纳米棒阵列组成,具有良好的结晶度和明显的(002)取向,Ti(OC_4H_9)_4浓度越大,TiO_2纳米棒结合的越紧密,样品在紫外光区和可见光区都有良好的光吸收性,浓度为0.05mol/L时禁带宽度最小为2.96 e V;增大盐酸比例,会导致薄膜紫外吸收边带发生蓝移现象。
