Abstract
ZnO nanorod arrays were synthesized with simple chemical vapor deposition technique with template without using catalyst by controlling the growth time and condensation growth. The surface morphology of nanostructure were characterized by using field emission scanning electron microscopy (FE-SEM), we found that the ZnO nanorod arrays were uniformly covered on substrate. The extremely strong ZnO (0002) peaks were observed by using X-ray diffraction (XRD), shown the preferred (0001) orientation and high crystalline quality of the ZnO nanostructures. The optical properties were investigated by using photoluminescence (PL). These results showed the contribution of green-yellow emission attributed to the strong inner reflection and scattering. Our results indicating that the uniform ZnO nanorods arrays can be synthesized by using a simplified method. Furthermore, they will be implemented as application for nanodevice fabrication or for gas sensors and solar cells.
