摘要： 研究了B, F, S梯度掺杂TiO2薄膜的光催化活性，考察了晶相结构及吸收光波长的变化. 结果表明，离子单掺杂或共掺杂后TiO2薄膜的光催化活性均优于表面掺杂的TiO2薄膜，共掺杂TiO2薄膜的光催化性能优于单掺杂的TiO2薄膜，离子三掺TiO2薄膜对品红的最佳降解率可达81.11%，与离子间的协同效应有关.

Abstract: Photocatalytic activities of B, F and S gradient doped TiO2 thin films were studied. The microstructure and optical property were characterized. The results showed that the B-F-S doped TiO2 thin film using gradient doping method exhibited much higher photodecomposition activities than using surface doping process. The best degradation rate of magenta by three ion doped can reached 81.11%, which was due to the synergistic effect between B, F and S ions.
