Effects of Na₂SO₄ Concentrations on Electrodeposition of ZnO Film

Abstract:

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.
