Abstract ZnO nanocrystals with different sizes and morphologies were synthesized through using zinc acetate as precursor without surfactants under reaction temperature 80 ℃ and reaction time 30 min in different kinds of alcohols as solvent (ethanol, n-propanol and 1-butanol) by changing alcohol to water ratio, pH and precursor concentrations. The synthesized ZnO nanocrystals were characterized by using transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV-visible absorption spectrum. The results show that the obtained ZnO nanocrystalline samples could give apparent absorption peaks in the range of 350—365 nm. The sizes and aggregations of the synthesized ZnO nanocrystals could increase by decreasing alcohol to water ratio and the polarity of alcohol. At the same time, the absorption peaks did not changed anymore by changing the precursor pH values.
