Novel petal-like ZnO crystal synthesized by organic solution method

Inorganic Materials Aims and scope

Abstract

ZnO crystals with different morphologies have been synthesized by an organic solution method using Zn(CH3COO)2 · 2H2O and polyvinylpyrrolidone as precursors. X-ray powder diffraction, field emission scanning electron microscopy and transition electron microscopy were used to characterize the obtained samples. The results showed that novel petal-like ZnO particles could be obtained when the molar ratio of Zn2+/C = O was 1 : 4. The particle had uniform diameter in 200–300 nm and with good dispersibility. Otherwise, octahedron shaped particles with sub-crystalline were achieved when the molar ratio of Zn2+ to the carbonyl group of polyvinylpyrrolidone was 1 : 2 or 1 : 8.
