Synthesis of Disk-Like and Flower-Like ZnO Nanostructures by Sodium Dodecyl Sulfate-Assisted non-Basic Solution Process

Disk-like and flower-like ZnO nanostructures were prepared in alcoholic solutions with SDS-free and various sodium dodecyl sulfate (SDS) concentrations by a non-basic solution method. In all cases, the obtained crystals exhibited the crystal structure of wurtzite ZnO and photoluminescence at UV and green regions. The ZnO grown in the SDS solution have a morphology of aggregated disk-like and flower-like structures. The origin of morphology different of the ZnO crystals is explained by a chemical interaction between surface of ZnO seed crystal and SDS micelles.
