Resumen : | ZnO has received increasing attention and been recognized as a promising candidate for applications due to its optoelectronic properties in the UV range. The ZnO is grown by the technique of Chemical Bath Deposition activated by microwaves (CBD- tW). X-rays sca ttering yields a hexagonal polycrystalline wm1zite type structure. The Raman spectra present fom main peaks at 444, 338, 104 and 78 cm•1 associated to the modes E/ ;x", (E/"K"- £/"" ), £/""' and an unidentified band. The 300 K photoluminescence presents visible/UV radiative bands associated to vacancies of zinc and oxygen . In addition, it was carried out energy dispersive spectroscopy (EDS) measmements on the films to determine their stoichiometry, relating the intensity of radiative bands associated to oxygen and zinc vacancies. |
