Abstract	In this paper, the molecular structures of tungsten trioxide $(WO_{3})$ crystal film surfaces are studied by AFM.IPC-208B, and their XRD spectrums are also analyzed. Two types of crystal film are: $WO_{3}$ sol-gel film adulterated with platinum and $WO_{3}$ magnetron ion sputtering film adulterated with platinum. The studies on $WO_{3}$ sol-gel film adulterated with platinum show that it has been cubic crystal after annealing at 460degC, its crystal cell includes a $WO_{6}$ octahedron in which six oxygen ions locate in the center of six planes of cube and one tungsten ion locates in the center of cube, its lattice parameter is about 0.75 plusmn 0.05 nm, its natural growth surface is (002) plane on which its one cell includes five ions, four oxygen ions locate in the culminations of quadrangle and one tungsten ion locates in the center of quadrangle, and the distance between two adjacent oxygen ions is about 0.55 plusmn 0.05 nm. Meanwhile the studies on $WO_{3}$ magnetron ion sputtering film adulterated with platinum find that it has also been plate crystal after annealing at 400degC , its crystal cell includes four tetrahedrons, its natural growth surface is (106) plane on which its one cell includes three tungsten ions and seven oxygen ions or two tungsten ions and eight oxygen ions, these ions locate in the culminations of four coterminous quadrangles, and its lattice parameters are about 1.35 plusmn 0.05 nm and 0.35 plusmn 0.05 nm, respectively. The above results on molecular structures of $WO_{3}$ crystal film surfaces have never been seen in overseas or home reports.
