The selectively manipulated growth of crystalline ZnO nanostructures

Abstract

Aligned ZnO nanorods on film, tetrapod nanowires and nanotubes have been selectively fabricated by a simple one-step route and characterized by x-ray diffractometry (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) and photoluminescence (PL). PL spectra exhibit different intensity of the green emission relative to the UV emission for different nanostructures. The effects of the process parameters on different nanostructures have been discussed. The wettability of well aligned nanorods on film was investigated, which reveals a super-hydrophobicity.
