Fabrication and Characterization of ZnO Nanorod Arrays Grown on Nickel-Coated Polyester Fiber

Abstract

Vertical-aligned arrays of zinc oxide (ZnO) nanorod were grown on nickel-coated polyester s for future development of ZnO nanorod-based solar cells. ZnO nanorods with aspect ratio of three were deposited by chemical solution deposition (CBD). Besides, an underlying ZnO seed layer was introduced to grow large-area and continuous layer of ZnO nanorods using pulsed laser deposition (PLD). Structurally, dominating XRD diffraction of the ZnO nanorod arrays was occurred at lattice plane (002) and a specific Raman spectrum was also obtained. Optically, bandgap energy of the ZnO nanorods was 3.95 eV. The ZnO nanorods with full-width at half-maximun (FWHM) of about 16 nm were excited normally from ultraviolet laser source of λ=266 nm and released edge-emission of λ=383 nm. On the basis of our results, high quality ZnO nanorods have been successfully fabricated on nickel-coated polyester fibers.
