Surfactants play an important role in the synthesis of semiconductor materials. The growth and crystal behavior can be modified by selective adsorption of surfactants on the crystal surface, which allows controlling their shape. Using surfactants and controlling the surfactant concentration in the growth solution, ZnO nanostructures of various morphologies were synthesized by the hydrothermal method at 95°C. The effect of the surfactant presence in the growth solution on the morphology of the ZnO structures was studied. As a result of the study, a correlation was obtained between the ZnO particle size and the surfactant concentration in the growth solution. Scanning electron microscopy images showed that the morphology of zinc oxide changed from rod-shaped to film-shaped upon adding 5 wt% and 10 wt% surfactant. X-ray diffraction (XRD) spectroscopy results indicated the presence of zinc oxide phase in all samples. It is found that the diameter of nanorods increases with increasing surfactant concentration. The systematic growth mechanism with increasing surfactant concentration is studied. The obtained results will help in growing selective ZnO for many functional applications. The grown samples can be used as transparent conducting electrodes and photocatalysts, as well as the basis for gas sensors and electrochemical sensors.
