Effects of Na2SO4 Concentrations on Electrodeposition of ZnO Film
The effects of Na2SO4 concentrations on the electrochemical deposited ZnO films have been investigated using scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X-ray diffraction (XRD). The results show that Na2SO4 concentration plays a very important role in directing the growth of films from rod-like ZnO to plate-like zinc hydroxysulfate under fast hydroxylation. At a lower Na2SO4 concentration, the ZnO nanorods tend to be produced on the substrate. At a higher Na2SO4 concentration, zinc hydroxysulfate plates can be preferentially formed.
