Abstract
The effects of Zn(OAc)2 concentrations and chemical nature of supporting electrolytes on the galvanic deposition of ZnO have been investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive X-ray (EDX) microanalysis. The results show that the taper-like ZnO crystals are apt to be produced at lower Zn(OAc)2 concentrations, while the rod-like ZnO crystals tend to be grown at higher Zn(OAc)2 concentrations. The photoluminescence of as-prepared ZnO nanorods shows that there exist a strong UV emission band, a broad blue band at 468Â nm, and a very weak green band at 550Â nm. The blue-shift of UV emission is attributed to the Cl doping of ZnO in chloride electrolyte.
