and films were prepared by spray pyrolysis technique and their structural and optical properties were examined. The X-ray diffraction of these films shows that the rhombohedral structure of BFO film is modified and reduced toward the monoclinic or tetrahedral structure at 10 at.% of with higher crystal symmetry. The structural transition is in favour of reduced oxygen vacancies in films. The transmission electron microscopy was used to know the crystal structure and the particle size of the films. The band gap in the film (Eg≈2.55 eV) has significantly increased in comparison to the film (Eg≈2.32 eV).
