Title

Study of structural and optical properties of NixCo1-xDyyFe2-yO4 nanomaterial synthesized by sol-gel autocumbustion method

Abstract

The present work reports the synthesis of ferrite powders having compositions: NixCo1-xDyyFe2-yO4, y = 0.025, x = 0, 0.1, 0.2, 0.3 and 0.4 by using nitrates of nickel, cobalt, dysprosium and, iron as starting materials. The preparation of ferrite powders was carried out into two steps. In first step the auto combustion of a gel obtained from stoichiometric mixture of starting materials with citric acid as burning agent was carried out. This was followed by the annealing of auto-combusted precursor at elevated temperature of 560 oC. The resultant as-annealed powders were characterized by the using different physical techniques: TGA/DTA, X-ray diffraction (XRD), UV-Visible spectroscopy, and FTIR spectroscopy. The temperature of ferrite was confirmed by using thermal analysis: TGA/DTA studies. The structural studies by using XRD revealed the formation of pure ferrite powders with cubic spinel symmetry. The values of the band gap by using UV-Visible spectroscopy were found to be in range of 1.638 to 1.673 eV. The FTIR spectra supported the XRD results.

Key Words

Ni-Co ferrite; Auto-combustion, UV-Visible, FTIR, TGA/DTA.
