| 摘 要： | 将不同比例的Ti粉和Fe粉的混合粉末加入到质量分数为30%的H2O2溶液中,然后把Ti片浸入其中,保持80℃低温反应72h,在Ti片上形成了Fe掺杂TiO2薄膜。利用X射线衍射仪,扫描电子显微镜,紫外-可见光谱仪等多种手段对薄膜的结构及光吸收性能进行了研究。结果表明,在Ti片表面形成了结构较为疏松的锐钛矿相Fe掺杂TiO2薄膜;与未掺杂的TiO2薄膜相比,不同Fe粉含量生成的Fe掺杂TiO2薄膜的紫外-可见光吸收边均发生明显红移,禁带宽度均有所减小;掺Fe量为3%时,TiO2薄膜的禁带宽度减小至3.04eV。 |

| Abstract: | The mixed of Ti powder and Fe powder with different proportions was put into 30% hydrogen peroxide solution,then Ti fo ils were soaked into the solution then Ti foils were soaked into the solution at 80℃ for 72 h.Th e Fe-doped TiO2 thin films were deposited on Ti foils.The structure and phot o-absorption property of Fe-doped TiO2 thin films were characterized by X-ray diffraction,scanning electron microscopy and UV-Vis absorption spectroscopy. It turned out that loose Fe-doped anatase TiO2 thin films were formed on Ti foils.Fe-doped TiO2 thin films with different Fe contents all indicated redshifted absorption features and the band gaps all reduced compared with the undo p ed TiO2 thin film.The band gap of 3% Fe-doped TiO2 thin film decrease d to 3.04 eV. |
