ABSTRACT:
Nanoscale magnetic particles show an interesting area of study and they find applications in various fields. In the present study the magnetic nanoparticles of Fe2O3 were synthesized through sol-gel method and were characterized by using the X-ray diffraction analysis (XRD), Atomic Force Microscopy (AFM), FTIR and Particle Size Analyzer at room temperature. XRD analysis confirms that all the samples exhibit single phase hexagonal structure and excludes the presence of any secondary phase. The average crystallite size calculated from XRD data was found to be between 18-30 nm for the samples sintered at temperature ranging from 100ºC to 1000ºC. Tapping mode 3-D AFM image of Fe2O3 nanoparticles shows different shapes and sizes of nanoparticles aggregates. The nanostructure tend to form rather than homogeneous aggregates having pyramidical structure, which consist of parallel chains between 10-30 nm in breadth with different orientations. The roughness measurements of the samples showed that the surface is little bit smooth with some cracks. FTIR study showed that the bands near 473 cm-1 and 540 cm-1 were characteristic absorptions bands of Fe–O bond for Fe2O3 nanoparticles. Particle size Analyzer data showed that the average particle size is 19.82 nm for as-synthesized Fe2O3 nanoparticles.
