摘要：

Fluorine-doped TiO2 thin films featuring columnar structure were prepared on fluorine-doped tin oxide (SnO2:F) substrate using a sol-gel method. The F doping ratios were varied in the range of 0-8 %. The effect of [F]/[Ti + F] ratio on the structural, morphological, optical, photocatalytic and low-emissivity properties has been investigated in detail. X-ray diffraction studies revealed that all the composited films are mainly composed of anatase TiO2 and rutile SnO2 without other phases. The prepared TiO2:F films possessed the columnar morphology with the single layer thickness ranging from 28 to 31 nm. The best photocatalytic activity was obtained for the films with 4 % F doping ratio which is mainly attributed to the highest crystallization and crystallite size. The transmission and hemispherical emissivity of the composite films could still reach approximately 70 % and 0.20, which match the requirements of the Chinese National Standard (GB/T18915.2-2002), promoting the films for the practical applications.
