Abstract

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-μW). X-rays scattering yields a hexagonal polycrystalline wurtzite type structure. The Raman spectra present four main peaks at 444, 338, 104 and 78 cm-1 associated to the modes E2high, (E2high - E2low), E 2low 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) measurements on the films to determine their stoichiometry, relating the intensity of radiative bands associated to oxygen and zinc vacancies.
