摘要

Nanoferrite materials had been synthesized to produce new alternate substance for reducing the rare or high cost of industrial materials. In this work, the Zn0.5Mg0.5-xLi2xFe2O4 nanoferrite (x = 0.00, 0.10, 0.20, 0.30 and 0.40) was prepared by co-precipitation approach. Structural and optical properties were investigated for the Zn0.5Mg0.5-xLi2xFe2O4 series by X-ray diffraction (XRD), Fourier transforms infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopies. The XRD data showed that all samples of Zn0.5Mg0.5-xLi2xFe2O4 series possess a cubic spinel with a space group (Fd-3m) structure and crystallite size decreased from 116 to 96 nm with a doping ratio. Lattice parameter founded to increases with Li1+ ratio that result in the larger ionic radius of the Li1+ cation. FTIR result verified the formation of spinel structure by appearance of the absorption bands around 420, 580 cm-1. The energy band gap computed for Zn0.5Mg0.5-xLi2xFe2O4 samples and it founded in the range of 3.28 - 3.12eV.
