Abstract

Using chemical bath deposition(CBD) method we fabricated hexagonally, vertical aligned ZnO nanorod arrays on glass. XRD pattern of the sample shows only (002) diffraction peaks were observed, indicating excellent (001) orientation and well vertical alignment of the ZnO arrays. SEM results of samples fabricated under different condition show that we can control the diameter of the nanorods by using growing solution with different concentration. To attain the desired length, we ushered a novel multi-growth method, with which we obtained ZnO nanorod arrays thicker than 10μm. PL spectra of the sample shows strong UV emission.
