Abstract:

Zinc oxide (ZnO) nanorods were grown on three kinds of substrates by means of the chemical solution deposition (CBD) method. The crystal structure, morphologies and photoluminescence properties of the  nanorods were studied by means of X\|ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and photoluminescence spectroscopy (PL). The results show that the products, ZnO nanorods were uniformly distribationed on the substrate, the crystallization quality of the ZnO on the ITO conducting glass and bare glass substrates are better than that of  the sample on the Si substrate. And the nanorods grown on the bare glass have the most  coverage density and their tropisms are unity. The ZnO nanorods grown   on the Si substrate have the best photoluminescence. The small shift in the UV emission was caused by the stress due to the different sizes of the nanorods.
