Synthesis of transition metal (Cu, Fe and Co) doped ZnS nanostructures
2012
Undoped, Cu-, Fe- and Co-doped ZnS nanostructures were synthesized by solvothermal reaction of Zn(CH 3 COO) 2 ·2H 2 O and (NH2)2CS with PVP dissolved in the hydrazine hydrate. X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy dispersive x-ray spectroscopy (EDX) were employed to characterize the structure and morphology of the product. The results showed that copper incorporation in the ZnS induced a phase transformation from hexagonal wurtzite to cubic blende structure, and the morphologies of doped ZnS are found to be Cu, Fe and Co-doped concentration dependent.
