Nanocrystalline double-layer film of TiO2/ZnO was prepared by pulsed laser deposition on quartz substrate and their microstructure, optical property and photocatalysis were investigated. The first/bottom ZnO layer grew on its [001] direction of the wurtzite structure, while the second/top TiO2 layer consisted of nanorods grown on the [001] direction of its anatase structure. The TiO2/ZnO film showed improved photo-absorption in visible light in the UV-visible absorption spectrum; and showed weaken UV emission and enhanced deep level emission in the photoluminescence spectrum. By the degradation of methyl orange and methylene blue, the TiO2/ZnO film exhibited evident enhanced photo-degradation efficiency in a wide wavelength range. That can be explained by the enhanced wavelength response in visible range, more effective use of irradiation light and the retarded recombination of electron-hole pairs in the double layer films.
