| 摘 要： | 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。

| Abstract: | Iron（1%）-doped TiO2nano-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 obvious red shift, and absorbance also increased greatly. |
