Influence of immerse time on the properties of zinc oxide nanostructures

Zinc oxide (ZnO) is an emerging optoelectronic material in large area electronic applications due to its various functional behaviors. We present the fabrication and characterizations of ZnO nanostructures. The ZnO nanostructures consisting of nanorods were synthesized using sol-gel hydrothermal technique on oxidized silicon (Si) substrates. In the fabrication of ZnO nanorods, the oxidized Si substrates were immersed in ZnO aqueous solution for different times ranging from 3.5 hours to 5 hours. The surface morphologies of the ZnO nanorods were examined using scanning electron microscope (SEM). In order to investigate the structural properties, the ZnO nanorods were measured using X-ray diffractometer (XRD). The optical properties were measured using photoluminescence (PL) spectrophotometer. The influence of the immerse time on the properties of the realized ZnO nanostructures will be revealed and discussed in this paper.
