Highlights

► Precursor Zn(salen) was synthesized by a solid–solid reaction, and then ZnO nanoparticles were obtaioned by thermal treatment of Zn(salen) at 500 °C for 5 h.

► Room temperature photo-luminescence spectrum of ZnO nanostructures are dominated by green emission attributed to oxygen vacancy related donor–acceptor transition.

Abstract

ZnO nanoparticles, 10–20 nm in size, were synthesized by heat treatment in air at 500 °C 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.
