Surfactant dependent growth of twinned ZnO nanodisks

• Preparation of ZnO nanodisks by using SDS and CTAB separately.
• Preparation of twinned ZnO nanodisks by using same surfactants together.
• Investigation and characterization of the structural and growth mechanism.

Regular hexagonal twinned ZnO nanodisks were successfully prepared from nanodisks using a controlled hydrothermal method with the assistance of double surfactants. The products were characterized using X-ray powder diffraction. The morphologies of ZnO nanostructures were characterized in detail using field-emission scanning electron microscopy and high-resolution transmission electron microscopy. Based on the experimental results, a growth mechanism for hexagonal structure was proposed.

For the first time after using double surfactant, we prepared twinned ZnO nanodisks. Before twinning, both the surfactants were used to make nanodisk structures, then assembled to twin the nanodisks by a controlled hydrothermal method.Figure optionsDownload as PowerPoint slide
