| Abstract: | Using Zn（CH3COO）2·2H2O as zinc source and triethanolamine（TEA） as alkaline source,large-scaled and monodispersed ZnO porous and solid nanospheres are successfully synthesized via a template-free sonochemical process at the ambient condition.The structures,morphologies and optical properties of as-prepared ZnO products are investigated by XRD,FESEM,IR,UV-visible spectrum and photoluminescence spectrum（PL）.By careful comtrolling the concentration of TEA,porous ZnO nanospheres with the diameters of 120~260 nm and solid ZnO nanospheres with the diameters of 200~340 nm are obtained,respectively.These ZnO nanospheres are self-assembled by 20~25 nm nanoparticles.The possible formation mechanism of spherical nanostructures is also discussed. |
