Abstract

ZnO is an n-type, wide band gap II-VI compound semiconductor with a band gap energy of 3.37 eV at room temperature. ZnO possesses a large exciton binding energy hence its nanowires and nanorods have been regarded as one of the most promising materials for nanoscale electronic and optoelectronic devices such as laser diodes, optical detectors and switches. Several techniques have been utilized to fabricate ZnO nanoscale materials, such as molecular beam epitaxy, sputtering, chemical vapor deposition, spray pyrolysis, pulsed laser deposition (PLD), anodic alumina oxide (AAO) template, electrochemical deposition, and aqueous solution deposition methods. In an attempt to prepare the best quality nanowires, we chose a chemical solution method. This paper reports the preparation and characterization of nanorod arrays of ZnO on ITO glass substrates which were pre-coated with ZnO. The structural and optical properties of ZnO nanorod arrays were investigated using scanning electron microscopy, X-ray diffraction and photoluminescence (PL) techniques. It was shown that ZnO seed layer annealed at 300 °C with a particle size of 10-20 nm appears on the ITO substrate. The introduction of annealed ZnO nanoparticles seed layer is required for the formation of well-aligned ZnO nanorods. The ZnO nanorod arrays with a diameter of 40-70 nm and a length of 200-300 nm were obtained. Besides, a strong UV emission in the PL spectrum revealed the good crystal quality of ZnO nanorods.
