Abstract:

Zinc Oxide (ZnO) nanowires with hexagonal structure were successfully synthesized by chemical bath deposition technique. The obtained nanowires were characterized by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and spectrophotometer. The XRD pattern of the samples revealed that ZnO nanowire has a hexagonal crystallite structure and further showed that the crystallite size supported by Scherrerā??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.
