Growth of Nanorods and Nanowires of ZnO by Chemical Route

The orientation control of ZnO nanocrystallites and the ability of assembling them in three dimensional arrays are essential for creating functional materials, such as solar cells, photonic devices, etc. In this article, the hydrothermal growth of large surface area, high quality, ZnO nanorods and nanowires on glass substrate is reported. This route permits large scale fabrication of ZnO nano rods and wires with a relatively low cost and potentially applicable in optoelectronic nano devices. The orientation of ZnO rods and wires can be controlled by controlling the temperature, pH of the reacting systems and the concentration of reactants. The products prepared under different conditions of the reacting precursors confirmed that the resulted nanorods and nanowires are single crystalls of hexagonal wurtzite structure and highly oriented along [002] direction in their structure
