摘要：

Zinc substituted manganese ferrite Mn1-x ZnxFe2O4 (x = 0.00, 0.20, 0.40, 0.60, 0.80, 1.00) magnetic nanoparticles were synthesized using low cost and environmental friendly co-precipitation method. The structural, infrared and optical properties of synthesized material were characterized by XRD, TEM, FTIR, EDX and UV-Vis spectroscopy respectively. The XRD result confirmed the formation of good crystallization with a single-phase cubic spinel structure and Fd3m space group. Also determined crystallite size decreases from (20-10 nm). The FTIR spectra confirmed the formation of ferrite phase and tetrahedral and octahedral vibrations. The UV-Vis spectroscopy determines the direct energy bandgap which increases from similar to 2.26 to similar to 2.63 eV.
