Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.
