Abstract:
ZnO flower-like nanostructures were grown on Si substrates by thermal chemical vapour deposition method with Au catalyst assisted. The structure obtained on Si substrate composed of hexagonal ZnO nanorods which have hexagonal wurtzite structure with lengths and based diameters in the ranges 200-300 and 100-130 nm respectively. The individual nanorods have a sharp tip in a size less than 100 nm. This sharp tip is suitable for probe and sensor applications. Detailed structural characterisations of the XRD pattern revealed that the ZnO flower-like nanostructures are single crystalline with the wurtzite hexagonal phase and the growth direction along c-axis. The morphologies and the crystal structures of ZnO flower-like nanostructures were characterised by SEM and XRD. Details of the synthesis technique and its properties were explained in this paper.Keywords: ZINC OXIDE; FLOWER-LIKE NANOSTRUCTURE; WURTZITE STRUCTURE; NANORODS
