摘要：以钛酸丁酯为主要原料，在乙醇－水体系中采用溶胶－凝胶法，制备掺杂Li＋、 Mg2＋、 Al3＋三种金属离子的溶胶前驱体，利用浸渍提拉法制备TiO2薄膜。结果表明，掺杂金属离子的薄膜的最大吸收波长均在300～310 nm处；掺杂Li＋、 Mg2＋的薄膜的吸收光谱发生蓝移，且随掺杂量的增多蓝移现象减弱；掺杂Al3＋的发生红移，且随掺杂量的增多红移现象减弱。掺杂Mg2＋的吸光性能较好。扫描电镜照片表明试样的表面平整，颗粒均匀。
Taking C16 H36 O4 Ti as the main raw material and using the sol-gel method in ethanol-water system, the sol precursor of mixing Li＋, Mg2＋, Al3＋three metal ions was prepared , using the pulling dipping , the TiO2 films were prepared.The results showed that the maximum absorption wavelength of the thin films with metal ions were between 300~310 nm.The absorption spectrum of the film doping with Li ＋, Mg2＋brought about blue-shifted, and with the increase doping with Li＋, Mg2＋, the blue shift became weakened.The absorption spectrum of the film doping with Al 3＋brought about red-shifted , and with the increase mixing of Al 3＋the red shift became weakened.The absorbance performance of the film with Mg2＋was better than others.The scanning electron micrographs showed that the surface of the sample was smooth, and the particles were well-distributed.
