Abstract
As-grown and antimony (Sb) doped ZnO nanowires (NWs) have been successfully grown on Au-coated Si(1 0 0) substrate by vapor-liquid-solid (VLS) method. The growth temperature was kept at 950˚C purposefully to make Au layer act as a nucleation site. The length of Sb-doped ZnO NWs increases largely ~ 12 times longer than those of the undoped ZnO NWs; however the earlier structure is thinner than the later. Scanning electron microscopy and X-ray diffraction measurement of Sb-ZnO wires present good NWs morphology and high purity and crystallinity of the samples, respectively. Similarly the photoluminescence (PL) spectra of as-grown and Sb-doped ZnO NWs reveal the band-to-band transition without the significant defect level emission. However, PL peak due to the Sb-doped ZnO nanowires exhibits red shift as compared to that of as-grown ZnO NWs. Our results have been compared with the literature and interesting features have been discussed.
