ABSTRACT
Zinc Oxide (ZnO) nanowires with hexagonal structure were successfully synthesized by chemical
bath deposition technique. The obtained nanowires were characterized by scanning electron
microscope (SEM), X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and
spectrophotometer. The SEM micrographs revealed the morphology of ZnO nanowires with
diameter between 170.3 and 481nm and showed that the pH of the bath solution, 8.1 is the
optimized value to form ZnO nanowires with hexagonal shape. The XRD pattern of the samples
revealed that ZnO nanowire has a hexagonal crystallite structure and further showed that the
crystallite size supported by Scherrer’s equation increase with increasing annealing temperature
(0.536 nm, 0.541nm, 0.557 nm at 1000C, 1500C and 2000C) respectively. The EDX analysis
revealed the elemental compositions of samples and confirmed the presence of Zn and O. The
results of the optical analysis showed that ZnO nanowire has high absorbance in the ultraviolet
and infrared regions with high transmittance in the visible region. The results further revealed
that the absorbance of the nanowire increase with increasing annealing temperature. Its high
absorbance in the ultraviolet region suggest that it can be use as solar harvester for trapping
solar energy for photovoltaic panel which is capable of converting sunlight radiation directly to
electricity for commercial or industrial purpose.
