摘要：
ZnO nanorods were synthesized on sol-gel prepared ZnO seed layer over p-Si substrate. The X-ray diffraction (XRD) of nanorods showed c - axis orientation perpendicular to the substrate. The Field emission scanning electron microscopy (FESEM) of the surface of the ZnO film showed vertical ZnO nanorods with hexagonal crossection. The diameter of the nanorods was of the order of 200 nm. The optical reflectance of the nanorod showed an absorption edge at the band gap of ZnO. The photoluminescence of nanorods showed UV emission at room temperature. The intensity of emission showed dependence on nanorod diameter. The current-voltage characteristics of ZnO nanorod films showed rectifying behaviour.
