Abstract

• The main aim of the research work is to study the preparation and characterization of silver doped bismuth ferrite, Ag-BiFeO3 by co-precipitation method. In this method, Ag-BiFeO3 nanoparticles were prepared by using bismuth nitrate, ferrite nitrate and silver nitrate as starting materials with different ratios (1:1:0.125, 1:1:0.25, 1:1:0.5 and 1:1:1) and the prepared silver doped samples were noted as S-1, S-2, S-3, S-4 respectively. The precursor powder was calcined at 500 C for 4 h. The prepared samples were characterized by XRD, SEM and EDXRF techniques. The ratio (1:1:1) of bismuth nitrate, ferrite nitrate and silver nitrate was selected as optimum ratio due to its high crystallinity and average crystallite size. Some physicochemical properties and optical properties of prepared Ag-BiFeO3 powder samples were also determined.
