EFFECT OF NICKEL DOPPING IN BIFEO3 NANORODS

BiFeO3 is one of the most promising multiferroic materials, since it can exhibit both ferroelectricity and antiferromagnetism at room temperature. Addition to that BFO is known to have an optical band-gap in the range of 2.5 ¿ 3.2 eV. This makes it an important material for future optoelectronic device applications. In this approach, Pure and Ni doped BFO thin films were successfully deposited on FTO substrate using spray pyrolysis system. The structural and morphological and optical properties of films were discussed well. The films structure were confirmed with XRD pattern, and it is observed that both the samples are polycrystalline in nature and the observed diffraction peaks are indexed to rhombohedral structure with R3c space group. Doping with Ni has been found to be desirable because it reduces the optical band gap and thus, can be used with much success for many optoelectronic as well as magneto-optical applications.
