Abstract	Different three-dimension (3D) nanotetrapods, containing club-like nanocrystals, nanotetrapods and four-foot-like nanocrystals were synthesized from Zinc sheet via CO$_{2}$ laser irradiation and coaxially transporting O$_{2}$. Different nanoproducts were fabricated by changing the content of oxygen in the experiment. The morphologies, components, phase structures and optical properties of the products were investigated by a field-emission scanning electron microscopy, an X-ray diffraction, an energy dispersed X-ray spectrometer and a photoluminescence spectroscope. The X-ray diffraction spectra were obtained on a Rigaku D/max 2500PC diffractometer. The experimental results reveal that high quality ZnO nanotetrapods can be fabricated on the special parameters, and growth of ZnO nanotetrapods depends on Vapour-Liquid-Solid(VLS) model, and the content of oxygen in the gas, namely, oxygen partial pressure is one of main factors to control morphologies and optical properties of ZnO nanotetrapods; these advantages above are important for realization of optoelectronic devices.
