Size, Structure and Optical Properties of Iron and Iron Oxide Nanoparticles Prepared by DC Arc Discharge in Liquid

Magnetic nanoparticles due to their widespread applications in various fields, have attracted special attention.There are several physical and chemical method to synthesis of iron and iron oxides nanoparticles which among themarc discharge in liquid is a physical and up-down rout to synthesis nanoparticles cheaply and by high yield, without anytoxic materials. Aim of this research is to study the effect of liquid environment including acetone, tetrahydrofuran anddeionised water, on size, structure crystal and optical properties of synthesised nanoparticles. In acetone andtetrahydrofuran different size α-iron nanoparticles prepared according to the different nature of liquid carrier media. Indeionised water XRD pattern demonstrated that the most crystal structure is α-iron. Optical transmission shows theabsorption of colloidal solution in deionised water in the optical characteristics of iron oxide. These results evidence theformation of iron oxide/α-iron core shell in deionised water.
