ZnO nanoparticles,10-20 nm in size,were synthesized by heat treatment in air at 500℃ for 5 h.,using [N,N-bis(salicylaldehydo) ethylene diamine]zinc(II),i.e.,Zn(salen),as precursor,which was obtained by a solvent-free solid-solid reaction.Heat-treated products were characterized by X-ray diffraction,Fourier transform infrared spectroscopy,scanning electron microscopy,and transmission electron microscopy.Room temperature photoluminescence spectra of ZnO nanostructures are dominated by green emission attributed to oxygen vacancy related donor-acceptor transition.
