Abstract

Fe doped ZnS nanoparticles, synthesized in microemulsion, consist of several nanocrystals with size of about 5 nm. The evolvement of the structure and morphology with the increase of Fe concentration indicates that Fe doping reduces crystallinity. The magnetic measurement shows that Zn _0.9Fe_0.1S is ferromagnetic at room temperature and the coercivity decreases with the increase of Fe concentration. Significant blue shift of absorption edge in the UV-vis spectra induced by Fe doping is observed. The X-ray absorption fine structure (XAFS) spectra of Fe K-edge indicate the Fe ions in ZnS lattice are trivalent and the local structure around dopant is analyzed.
