Title

STRUCTURE AND MORPHOLOGY OF NANOSTRUCTURED ZINC OXIDE THIN FILMS PREPARED BY DIPVS. SPIN-COATING METHODS

Pages

  603-609

Abstract

 In this study, we use dipping and spinning methods to coat glass slides with SOL-GEL ZNO THIN FILMs, composed of zinc acetate dihydrate, monoethanolamine (MEA), de-ionized water and isopropanol. The effect of the annealing temperature on the structural morphology and optical properties of these films is investigated. These ZNO films were preheated at 275oC for 10 min and annealed either at 350, 450 or 550oC for 60 min. As-deposited films, formed by amorphous zinc oxide-acetate submicron particles, are transformed into a highly-oriented ZNO after thermal treatment. The surface morphology, phase structure and optical properties of the THIN FILMs were investigated by scanning electron microscopy, X-ray diffraction (XRD) and optical transmittance. Both techniques produced NANOSTRUCTUREd ZNO THIN FILMs with well-defined orientation. The annealed films were transparent in the visible range with an absorption edge at about 375 nm and a transmittance of ca 85-90% with an average diameter of 40 nm. XRD results show the film was composed of polycrystalline wurtzite, with a preferential c-axis orientation of (002) and a single sharp XRD peak at 34.40, corresponding to the hexagonal ZNO. The grain size is increased by the annealing temperature. Both coating techniques create SOL-GEL ZNO films with the potential for application as transparent electrodes in optic and electronic devices.
