“…The slowest growing phase determines morphology of crystals [35,36]. Thus, under the experimental conditions and the kinetic difference in the growth planes, the slowest growing (0 1 0) planes dominate the crystal into the typical rectangular shaped structure (e).…”

“…2,[10][11][12] For example, platelets, flower-like clusters, tetrapods and multiple branched structures are reported. [13][14][15][16][17] Control of particle shape and size may be achieved by variation of: zinc precursor reagent type and concentration, pH, reaction temperature and pressure. 5,[10][11][12][13][14]21 Growth control additives, alternatively referred to as capping agents or structure-directing agents, are often employed to moderate ZnO particle shape.…”

ABSTRACT: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 as a function of hydrothermal reaction time. Polycrystalline hexagonal ZnO microrods first appeared after 0.5 h reaction time at 120 °C. These early stage rods were composed of stacks of hexagonal layers, each ~ 50 nm in thickness containing closely aligned assemblies of nanocrystallites < 20 nm in size. A further growth stage involving smaller pseudo-hexagonal columns nucleating and growing along <0001> from the (0001) basal layers of preformed polycrystalline hexagonal microrods was identified. For reaction times > 3h, the microrods were single crystals, as identified by TEM lattice imaging and electron diffraction, and many were in the form of double rods.

“…Metal oxide nanostructures are produced to have tremendous applications in the future [1][2][3][4][5]. Among them, magnesium oxide (MgO) is an exceptionally important material for use in catalysis, toxic waste remediation, as an additive in refractory, paint and superconducting products [6][7][8][9]. With its excellent thermodynamical stability, low dielectric constant and low refractive index, it has been used as a transition layer for growing various thin film materials.…”
