Large-scale and monodispersed zinc oxide spherical structures with different morphologies have been synthesized by a facile microwaveassisted chemical aqueous approach at reflux, using zinc acetate dihydrate, triethanolamine and deionized water as starting materials in the absence of the surfactants and organic solvent. By controlling the concentration of triethanolamine, the microwave irradiation time and the temperature of refluxing reaction, shape transformation of ZnO spherical structures could be achieved. The crystal structure and morphology of products were characterized by XRD, FT-IR, FESEM, EDS and TEM. The possible formation mechanisms for the shape transformation of ZnO crystals were proposed, as were considered to be three steps including triethanolamine-dominated hydrolysis process, Ostward ripening process and corrosion dissolution process. The present synthetic route is facile and controllable and gives a large-scale yield, indicating the products may be useful materials for optoelectronic nanodevices.
