Abstract ZnO tetrapod and multipod nanostructures were successfully synthesized without the presence of carrier gas and ca-talyst through a simple thermal evaporation method. The morphology, structure and photoluminescence properties of ZnO nanostructures were characterized by field-emission scanning electron microscopy, X-ray diffraction, transmission electron microscopy and fluorescence spectroscopy. The results demonstrated that the as-synthesized ZnO consisted of tetrapod and multipod nanostructures with a hexagonal wurtzite structure. The legs of the nanostructures had rod-like shape and grew preferably in the [0001] direction. The growth mechanisms of the ZnO tetrapod and multipod nanostructures were proposed. Room temperature photoluminescence (PL) spectra showed that the as-synthesized ZnO nanostructures had a strong green emission centered at 494 nm and a weak ultraviolet emission at 391 nm.
