Abstract

The ZnO quantum dots prepared via the solid-state pyrolytic reaction were studied. Our studies revealed the surface of ZnO quantum dots modified by amorphous ZnO. The as prepared quantum dots with sizes varying from 2-3 nm yields a blue shift about 0.15eV and shows an enhanced ultraviolet emission of 3-5 times over that of high quality ZnO nanoparticles.
