| 摘 要： | 本文采用水热法,以TiCl3和SnCl4·5H2O水溶液为前驱物,在180℃温度下反应24h.X能谱(EDS)显示:当前驱物中Ti3+、Sn4+离子比为4:1时,所得复合半导体纳米晶体中掺入的Sn的原子百分比为1;;当前驱物中Ti+、Sn4+离子比为1:1时,掺入Sn的原子百分比为2.8;.实验结果表明在TiO2金红相中进行晶格替代掺杂是比较困难的.

| Abstract: | In this paper, pure rutile Sn-doped TiO2 nanocrystals were synthesized by hydrothermal method, with TiCl3 and SnCl4 aqueous solutions as the precursor, at 180℃ for 24h. When the ratio of Ti3+/Sn4+ in the precursor solution was 4:1, EDS spectra show that the atomic percent concentration of the doped-Sn4+ in the synthesized rutile TiO2 nanocrystals was 1%. When the ratio of Ti3+/Sn4+ was changed to 1:1 ,the atomic percent concentration of doped-Sn4+ was up to 2.8%. It's indicate that it is hard for Sn atoms to dope into the lattices of rutile TiO2 nanocrystals by the way of lattice- substituting. |
