Low-Temperature Synthesis and Optical Property of ZnO Nanorod Arrays


Article Preview

Well-aligned ZnO nanorod arrays with 100-200nm diameter and about 1μm length were vertically grown on quartz substrate at relatively low temperature by a solution deposition method. The effects of reactant ratio, water-bath temperature, growth time on crystal structure were discussed. Microstructure of the arrays was investigated using X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM), optical properties were examined using fluorescence spectrophotometer. The results show that a Zn/C6H12N4 molar ratio of 1:1, bath temprature 70°C, growth time of 24h are the optimal condition for the preparation of densely distributed ZnO arrays. XRD and FE-SEM analysis confirmed that the ZnO nanorod is a single crystal with a wurtzite structure and the photoluminescence (PL) spectra exhibit coexistence properties of ultraviolet (UV), blue and green emissions.
