Abstract: Rodlike ZnO particles were directly precipitated by using zinc acetate and triethanolamine via a simple solution route at low temperature (90 ℃). The obtained ZnO particles were characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), thermogravimetry (TG) and differential scanning calorimetry (DSC). The formation mechanism of the rodlike ZnO particles was explained in terms of the theory of crystal nucleation and growth.

Key words: ZnO, Rodlike, Solution route, Direct precipitation
