“…It can be observed that these values are lower in comparison with those of the unheated Zn films. Such decreasing in the crystallite size in Zn films in consequence of thermal oxidation was also observed in case of Zn films evaporated onto glass substrates [16]. It can be also concluded from Figs.…”

“…The lower distance to the film substrate during film deposition and the greater growth rate for sample B can influence the lower crystallite size of sample B. A preferred (0 0 2) orientation of the crystallites was also observed for Zn film normally evaporated onto glass substrates [16], but this is not so strong as in this case. This fact indicates that, in the analyzed case, the intermediary ITO film substrate favors much more the respective texture.…”

“…The quasi-closed volume technique was used [15]. The temperature of the evaporation source, maintained constant during film deposition, was 723 K. Our previous investigations had revealed that the substrate position relative to the incident vapor during film deposition, influenced the structure of the respective samples [16]. For this reason, in this work, the incidence angle, b, of the incident vapor onto film substrate was taken as the deposition parameter.…”

“…In this case, an underlying oxide layer is formed on the surface of zinc particles before they are melted, leading to formation of structures with a ZnO shell and Zn-rich core. Obtaining of round-shaped ZnO structures by thermal oxidation of polycrystalline Zn thin films using long exposure times has been reported previously [7,23,24].…”

ZnO Micro- and Nanostructures Obtained by Thermal Oxidation: Microstructure, Morphogenesis, Optical, and Photoluminescence Properties

ZnO micro-and nanostructures were obtained through thermal oxidation of Zn powders at high temperature under air atmosphere. A detailed study of the microstructure, morphology, optical, and photoluminescence properties of the generated products at different stages of thermal oxidation is presented. It was found that the exposure time has a strong influence on the resulting morphology. The morphogenesis of the different ZnO structures is discussed, and experimental parameters for fabricating ZnO tetrapods, hollow, core-shell, elongated, or rounded structures by thermal oxidation method are proposed on the basis on the obtained results. Notoriously, the crystal lattice of the ZnO structures has negligible residual strain, although, the density of point defects increases when the thermal treatment is extended; as consequence, their visible luminescence upon UV excitation enhances.

“…Indeed, in the case of film deposition, certain crystalline planes may be favored in growth over the other, and therefore, the crystallites may grow with other planes perpendicular 18 or parallel to the substrate. 19 Consequently, other texture orientations of the grains on the film surface may occur. The XRD patterns from Figure 1 can confirm this assumption.…”

Zinc oxide based thin films have been grown on glass and stainless steel substrates in two steps; thermal evaporation from high purity metallic zinc and D.C. plasma oxidation. X-ray diffraction has shown that the films were polycrystalline nature and small predominant orientation at some specific planes. Analysis showed that plasma oxidation starts from the thermally evaporated leaf-like surfaces and produces a core-shell structure of ZnO on the metallic Zn. Increasing plasma oxidation power causes increased amount of ZnO volume and resistivity. Coin-type (CR2016) test cells were assembled in an argon-filled glove box and cyclically tested. The electrochemical performance of the films has been studied by cyclic voltammetry. The dependence of converted Li-ions on voltage profile of the films has been determined. It was found that the Zn/ZnO films exhibited highest the number of converted Li-ions at 175 W plasma oxidation conditions. Discharge capacity measurements revealed the double phase structures of Zn/ZnO exhibited significantly high reversible capacities. The high capacity and low capacity fade values were attributed to the high electrical conductivity and buffering ability of metallic Zn in the anodes.
