Abstract

Nano zinc ferrite powder was prepared by eco-friendly hydrothermal method. The prepared compound was well characterized by powder X-ray diffraction, scanning electron microscopy and UV-Vis spectophotometry. The compound formation was confirmed without any additional impurities. The PXRD data shows the crystallite size of the compound was about 6 nm. The SEM image showed the agglomeration of spherical nanoparticles. The UV-Vis spectrum and energy gap calculation confirmed the semiconducting behaviour of the sample. The magnetic properties of the compound revealed superparamagnetic nature at room temperature. These magnetic properties of the spherical nanoparticles are widely required in high performance devices like MRI contrast agent, cell separation and other biomedical applications.
