Abstract :
In this study, the aqueous solution method was employed to synthesize one-dimensional well-aligned ZnO nano-array on ITO glass substrate. We can find that the dimension of ZnO nanorod will changes with different growth temperature. X-ray diffraction patterns show that the nanorods are high-quality crystals growing along [001] direction with a high consistent orientation perpendicular to the substrate while the growth temperature is equal to 80. SEM images show that the average diameters of ZnO nanorods are about 60-90 nm by changing growth temperature. The smallest diameter of ZnO nanorods is observed while the growth temperature is equal to 75 degc. The UV/Vis spectra analyses show the absorption peaks appear at 330 nm, 370 nm and 390 nm while growth temperature increases from 65 degc to 85 degc.
