| Abstract: | The molecular structure of the surface of WO3 crystal film is studied by AFM and XRD spectrums. The results show that the sol-gel WO3 film doped with Pt is crystallized after annealing at 460℃. Its structure cell is a cube and includes a WO6 octahedron in which six oxygen ions locate in the center of six planes of the cube and one tungsten ion locates in the center of the cube. Its lattice parameter is （0. 75±0.05） nm, and its natural growth surface is （002） on which one cell includes five ions, four oxygen ions locate in the vertexes of the quadrangle and one tungsten ion locates in the center of the quadrangle, the distance between two adjacent oxygen ions is （0.55±0.05） nm. |
