Low-temperature hydrothermal synthesis of ZnO nanosheet using organic/inorganic composite as seed layer

Zinc oxide (ZnO) and Al-doped zinc oxide (AZO) nanorods were hydrothermally synthesized at low temperature using an organic/inorganic composite seed layer. The ZnO and AZO films had a sheet-like structure when ethanol was used as a solvent. The thickness of ZnO nanosheets can be controlled from 450 nm to 5.0 mu m by altering the concentration of a zinc source in a growth solution. The ZnO and AZO nanosheets have a flat surface and high transparency (more than 90%) of visible light. (C) 2012 Elsevier B.V. All rights reserved.
