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.

Result And Discussion

PXRD (Powder X Ray Diffraction)

Figure 1. shows the powder X-ray diffraction (PXRD) pattern of the as synthesized NZF. The diffraction pattern corresponds to a crystalline cubic spinel structure with space group Fdijbce.2013070105.m02 m (227). For the as prepared sample, the crystallographic phase analysis had been carried out using Shemero PXRD with monochromated Cu-Kα radiation and Ni filter at a temperature of 293K. The confirmation of the synthesized compound was done by comparing with the JCPDS card No- 89-7412. The average crystallite size for NZF was estimated from the Debby Scherrer formula and was found to be in the range of 5-10nm.
