Abstract

A series of ZnO crystals were fabricated by two separate steps including precursor precipitation and hydrothermal post treatment to compare the influence of precursor anions on morphologies of ZnO crystals. Sharp tip rod and flat end hexagonal column could be synthesized through hydrothermally treat ing the zinc hydroxide precursor containing carbonate ions, Zn5(CO32(6 in NaOH and NH3 ·H2O solutions, respectively, whereas just irregular ZnO nanoparticles were obtained through hydrothermally treating the precursor containing chlorideions, Zn5(8Cl2·H2O, in both of the alkaline solutions. Combining with the XRD, SEM and FTIR characterizations it was proved that carbonate ions of the precursor promoted the formation of ZnO crystals with well defined morphologies and the alkaline solutions used in hydrothermal treatment also played the key role in anisotropic growth towards one dimensional ZnO through controlling the growth rate..
