Abstract
Nanostructure such as quaternary alloy offers an unprecedented opportunity for alloy composition control in a wide range, unavailable with traditional epitaxial film materials. The technique of chemical co-precipitation has been employed to synthesize the NiZnFe

quaternary alloy nanostructure is elaborated by scanning electron microscopy (SEM) to measure the grain size. The optical properties are investigated via UV-visible spectrophotometry (UV-vis) and Fourier-transform infrared spectroscopy (FTIR) to research the absorption, transmission, reflection and bandgap for the mentioned NiZnFe
