The structure of the thin film was characterized by means of X-ray diffraction and UV-Vis absorption spectrum. The results of UV-Vis absorption spectrum indicate that the diameter of the TiO 2 nanoparticles is 2 nm. The results of X-ray diffraction indicate that the thin film is composed of organic and inorganic layers in alternately orderly arrangement. The distance between the organic layer and inorganic layer is 4.61 nm. The thicknesses of organic layer and inorganic layer are 2.58 and 2 nm, respectively.展开更多
