Large-scaled and monodispersed ZnO microspheres have been prepared successfully by using triethanolamine (TEA) aqueous solution as solvent at low reaction temperature ranging from 150 to 200 °C. The diameters of ZnO microspheres with narrow size distribution ranging (90%) and nice reproducibility via a simple hydrothermal route by using triethanolamine (TEA) aqueous solution as solvent. The as-obtained ZnO microspheres possess narrow size distributions (
