Investigation of the Magnetic and Optical Properties of Wurtzite Fe-Doped ZnS Nanorods

Article

Abstract

The optical and magnetic properties of Fe-doped ZnS nanorods have been investigated at room temperature. X-ray diffraction revealed the doped and undoped nanorods had a wurtzite crystal structure. The lattice constants of Fe-doped ZnS nanorods were less than those of the undoped counterpart. The elemental composition of the Fe-doped ZnS nanorods was verified by use of electron dispersive spectroscopy, which confirmed the presence of Fe. Compared with the undoped counterpart, a blue shift in the absorption edge was observed for Fe-doped ZnS nanorods. Blue and green emission lines were obtained from undoped and Fe-doped ZnS nanorods at 447 nm and 533 nm, respectively. Study of photoluminescence intensity revealed quenching at higher Fe concentration. The ferromagnetic character induced in Fe-doped ZnS nanorods was analyzed by use of M–H curves. Magnetic saturation initially increased with increased Fe doping up to 5%, then decreased with Fe doping up to 10%.
