Comparative Study of Structural, Optical, Morphological, and Magnetic Properties of BifeO3 Nanoparticles Synthesized Via Green and Chemical Methods
Abstract
BiFeO3 nanoparticles were synthesized via a green route using Strychnos nux-vomica leaf extract and a conventional chemical sol–gel method to study the effect of synthesis routes on their properties. XRD analysis confirmed phase-pure rhombohedral BiFeO3 for both samples. FTIR analysis was carried out to confirm the formation of the perovskite structure and to detect surface functional groups. FESEM analysis indicated a significant effect of phytochemicals in controlling particle growth and morphology. The green-synthesized BiFeO3 nanoparticles showed a reduced band gap (1.98 eV) as compared to chemically synthesized nanoparticles. Both samples exhibited weak ferromagnetism at room temperature, which may be due to size-induced spin canting. The results demonstrate that green synthesis is an effective method for tailoring the functional properties of BiFeO3 nanoparticles.
