Zinc oxide 'nanoleaf' structures have been synthesized at room temperature and pressure using the novel technique of pulsed laser ablation (Nd:YAG 532 nm) of a zinc target in an aqueous solution of sodium dodecyl sulfate(SDS). Transmission electron microscopy (TEM), selected area electron diffraction (SAED), high-resolution transmission electron microscopy(HRTEM), photoluminescence spectroscopy and UV-visible spectroscopy were used to study the morphology, nanostructure and optical properties of these ZnO nanostructures. The growth mechanism appears to involve an increase of the structural complexity from zero-dimensional nanoparticles to one-dimensional nanorods, and then broadening of these into two-dimensional 'nanoleaf' structures. Variations are discussed in terms of differences in the concentration of SDS and the laser ablation time.
