Synthesis and Characterization of Bismuth Ferrite Nanoparticles

Helen Merina Albert, Rubina Saleem

Abstract :

A multiferroic material, Bismuth Iron Oxide (BiFeO3, BFO) has been synthesized by sol – gel method. The prepared samples were characterized by X–ray diffraction of powder (XRD), UV analysis, Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDAX). The surface morphology studies confirm the growth of bismuth ferrite nanoparticles with their diameters in the range of 200nm to 500nm. The XRD analysis concludes the rhombocentered structure of synthesized nanoparticles. Topographical studies by SEM micrograph showed high level of agglomeration tendency in the sample and EDAX studies confirmed the elemental compositions in the sample. The BFO sample shows a decreasing trend of energy band gap Eg with increasing sintering temperatures was also observed. This absorption characteristics and narrow energy band gap has made pure phase BFO crystallites, a novel candidate in photocatalysis as well as photovoltaic applications. With change in synthesis conditions a transition from amorphous nature to crystalline behavior is observed.
