Abstract
Fe Doped CdS nanopaqrticles have been synthesized by a wet chemical method and TG used as a capping agent. The particle size of the nanoparticles calculated from XRD and optical methods has been found in the range 3-5 nm. The x-ray diffraction measurements showed that the nanoparticles have the structure of hexagonal phase. The broadening of XRD patterns indicate that the prepared CdS:Fe samples are nanostructures. The UV absorption results indicated that the doping increased optical band gap of nanoparticles which means the particle size decreased due to Fe doping. Also, effects of doping and capping agent concentration on the luminescence spectra of CdS:Fe nanoparticles investigated
