The characterization of the deposited films was studied with Bi dopant. The XRD analysis indicates that films are polycrystalline with a preferred orientation along (110) direction. AFM shows a porous morphology structure. The optical properties were obtained by UV–visible spectrophotometer, which show that these films are highly transparent above 85% in visible region with a slightly influenced upon Bi content. The energy gap was shifted from 3.1 to 2.6 eV, versus doping. Keyphrases: Bi: TiO2, SPD, Topographical, optical, structure
