Morphology Control of ZnO Particles in Liquid Phase

摘要

We realized morphology control of ZnO crystals and prepared ZnO particles with variety of shapes such as hexagonal, ellipse, two large needles with small needles and multi-needles. The morphology control was achieved by the control of super saturation degree of aqueous solutions. All of the particles showed X-ray diffraction of single ZnO phase. The control of crystal growth and particle morphology in this system would contribute to the development of future crystalline materials and devices.
