%X In this work, the <span style=\"white-space:nowrap;\">Mg<sub>1-x</sub> Zn<sub>x</sub> Fe<sub>2</sub> O<sub>4</sub></span> Nanoferrites (where x = 0.0, 0.2, 0.4, 0.6 and 0.8) was synthesized
using co-precipitation method. The investigation of structural and optical properties was carried
out for the synthesized samples using X-ray diffraction (XRD), Fourier transform infrared spectroscopy
(FTIR) and Ultraviolet visible spectrophotometer (UV-Vis). XRD revealed that the structure
of these nanoparticles is spinel with space group Fd3m and crystallite size lies in the range
21.0 - 42.8 nm. Lattice parameter was found to increases with Zn concentration and this may be
due to the larger ionic radius of the Zn&lt;sup&gt;<span style=\"white-space:normal;\">2+</span>&lt;/sup&gt;&nbsp;ion. FTIR spectroscopy confirmed the formation of spinel
ferrite and showed the characteristics absorption bands around 612, 1146, 1404, 1649 and 3245
cm&lt;sup&gt;<span style=\"white-space:normal;\">-1</span>&lt;/sup&gt;. The energy band gap was calculated for samples with different ratio and was found to be
4.77, 4.82, 4.86, 4.87 and 4.95 eV. The substitution was resulted in slight increased in the lattice
constant and that sequentially may lead to the slightly decreased in the energy gap.
