Structural Evolution of ZnO Polyol-Derived Nanomaterials
Zinc oxide (ZnO) has been intensively used in several technological applications. ZnO nanostructures with different morphologies are typically produced using the solid-vapor phase, hydrothermal methods, electrochemical deposition, molecular beam epitaxy and soft chemical solution methods. We have synthesized ZnO in diethyleneglycol using zinc acetate or zinc nitrate as a precursor compound. The morphology and the size of the resulting oxide particles were adjusted by using an acidic medium. The nanomaterials annealed at different temperatures (500-1000 °C) were structurally characterized and the morphology was observed. The synthesized ZnO nanocrystals have a hexagonal wurtzite structure and the maximum of UV-Vis spectrum was between 368-370 nm.
