Abstract

A new synthesis methodology is utilized to prepare ZnO nanoparticles with a narrow size distribution between 2 to 4 nm. The particle growth is found to be reaction time dependent. The dry powders of ZnO nanoparticles show a strong blue-shifted near-band-edge ultraviolet emission, and the size and size distribution of the particles did not exhibit noticeable change during solvent evaporation. Raman spectra show ZnO E22 (TO) phonon mode and other vibration modes that are attributed to the bound acetate group. The CO stretching mode in the Raman spectra is red-shifted to 1401 cm-1, indicating a strong adsorption of the acetate ligands onto ZnO surfaces.
