摘要
The crystallization of ZnO microrods by hydrothermal treatment of a suspension formed from reaction of zinc acetate and sodium hydroxide has been examined using scanning and transmission electron microscopy. Polycrystalline hexagonal ZnO microrods first appeared after 0.5h reaction time at 120 degrees C. These early stage rods were composed of stacks of hexagonal layers, each similar to 50nm in thickness containing closely aligned assemblies of nanocrystallites <20nm in size. Further growth of the microrods involved columns of nanoparticles extending from the basal layers of the preformed hexagonal stacks. Re-crystallization produced single-crystal microrods, many of which existed as twin particles.
