Influence Bismuth Dopant on Physical Properties of nanostructured TiO2 Thin Films

EasyChair Preprint 1835

Abstract

Nanostructured TiO₂ was prepared to utilize spray pyrolysis deposition (SPD). 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
