Abstract:

Zinc oxide nanostructures of rod, twisted-needle, petals and flower-like morphologies could be grown by microwave assisted chemical synthesis with excellent reproducibility. Each of the morphologies evolved through controlling the pH of the reaction mixture in between 5.5 and 12.0 before microwave irradiation. Morphology, structural, optical and optoelectronic properties of the nanostructures have been studied using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, micro-Raman spectroscopy and photoluminescence spectroscopy. It has been observed that both the crystallinity and defect structures in the nanostructures depend strongly on synthesis conditions. Mechanisms of morphology evolution and photoluminescence emission behaviours of the nanostructures are presented.
