Abstract
Iron doped zinc sulphide nanoparticles (ZnS: Fe) have been synthesized by co-precipitation method at room temperature. X-ray diffraction together with photoluminescence analysis established that iron occupies the lattice sites in host zinc sulphide lattice. The emission intensity is further quenched in iron doped nanoparticles as compared to un-doped one. This is attributed to the formation of electron-trap center by the dopants. Further, magnetic measurements reveal that pure zinc sulphide nanoparticles are diamagnetic whereas iron doped nanoparticles display a clear hysteresis even at room temperature.
