“…From the micrographs it has been found that the average thicknesses of the films were about 1 μm [27,28]. In addition to that, it has been realized that raising the annealing temperature normally increases the ZnO micro/nano structure diameters and lengths to some extent.…”

“…It has been thought that the annealing duration is one of the important factors to reach the willemite phase together with the annealing temperature. In our experiments we have reached a point that the optimum annealing duration for this kind of phase stabilization process that a minimum time span of 6 h is needed (see [27,28]). After an 800 • C annealing temperature up to 1050 • C, the ZnO absorption peak did not come back which was a sign that the stable Zn 2 SiO 4 willemite phase has been created for these annealing temperatures, even though the ZnO diffraction peaks are detectable in the XRD spectra.…”

In this work, zinc oxide (ZnO) thin films on quartz substrates were fabricated using the spin-coating method. Thermal annealings from 350 • C to 1050 • C have been performed in 50 • C increments and for two annealing durations (0.5 h and 8 h). X-ray diffraction (XRD) spectra, scanning electron microscopy micrographs, and UV-Vis absorption spectra of all the samples have been elucidated from mechanical and optical points of view. It has been observed that for all annealing temperatures, the crystal phase has been obtained. After 850 • C annealings, a new crystal phase related to Zn 2 SiO 4 (willemite) has also been appeared in XRD spectra. This phase remained stable up to 1050 • C annealing together with the ZnO crystal phase. It has been found that the nano/micro rod diameters of the ZnO crystals reach to a maximum (0.4 μm) at the 700 • C annealing for both annealing durations. For 650 • C annealings, ZnO nanorods appeared to be split into two homogeneous nanorods of length of 500 μm and of width of 0.35 μm (350 nm) which was not the case for all other annealing temperatures. After 950 • C annealings, ZnO nano/micro rods started to disappear and formed homogeneous ZnO thin films.

Copper oxide thin film is deposited on the glass slide using aqueous solution of copper chloride and hydrogen peroxide by using spray pyrolysis deposition technique. The deposited CuO thin film is adherence and homogeneity with high transparency in visible region. Investigation of CuO thin film for physical properties is done. By using UV -Visible Spectrophotometer optical properties like absorption, transmission, energy band gap, Absorption coefficient and extinction coefficient in the visible region (380 -1000 nm) are studied. The X-ray diffraction of CuO thin film is polycrystalline in nature with monoclinic crystal structure. The resistivity of Cuo thin film is studied using four probe methods.

The present paper presents the method for obtaining core/shell CuOZnO nanoparticles and nanocoatings by using a commercially available vacuum coating system. Initially generated Cu-Zn core/shell nanoparticles have been oxidised with a highly reactive atomic oxygen beam. Second-harmonic generation has been observed in the obtained samples. The dependence of second-harmonic intensity on the wavelength of the exciting radiation is shown in the paper.
