Photoluminescence and magnetic properties of Fe-doped ZnS nano-particles synthesized by chemical co-precipitation

► Zn1−xFexS nano-particles are synthesized by chemical co-deposition procedure. ► The Zn1−xFexS nano-particles are of single cubic zinc blende phase. ► The size of Zn1−xFexS nano-particles is about 3.3-5.5 nm. ► PL emissions of 425 nm and 470 nm have been found. ► Zn1−xFexS (x = 0.1) nano-particles present superparamagnetic performance.
