通过反胶束法制备掺铁（1%）的TiO2纳米溶胶，用浸渍提拉法在洁净的玻璃基底上形成不同条件下铁掺杂的TiO2（Fe-TiO2）纳米薄膜，分别在500℃和700℃温度下对陈化干燥的铁掺杂的TiO2凝胶进行热处理，得到不同粒径和不同堆积的铁掺杂TiO2纳米晶体。将不同制备条件下得到的（Fe-TiO2）纳米膜进行UV-可见光谱、SEM图像进行研究。实验表明：经过700℃热处理的铁掺杂的TiO2纳米晶粒比500℃铁掺杂的TiO2纳米晶粒大，且薄膜不同涂覆次数对TiO2纳米晶粒的大小与堆积均产生一定的影响；随着膜涂覆层数的增加，掺Fe-TiO2纳米薄膜的紫外可见吸收光谱出现明显红移，吸光度也大大增加。

Iron(1%)-doped TiO2 nano-sol was prepared by reverse micelles. Iron doped-TiO2(Fe-TiO2)nanometer thin films under different conditions were formed by dip-coating on a clean glass substrates, and iron doped TiO2 nano crystalline were made from aged iron doped TiO2 gel by heating under 500℃and 700℃. By analyzing the UV-visible spectroscopy and SEM images of the films ,we can find that the particle diameter of TiO2 nano crystalline under 700℃heat treatment is bigger than that under 500℃heat treatment, and different coating numbers had certain effect on the size and accumulation of TiO2 nano grain;With the increase of film coatings, the UV-visible absorption spectrum of Fe-doped TiO2 nano-films appear ob-vious red shift, and absorbance also increased greatly.
