“…The absorption edges were defined as the wavelengths at intersections that were obtained by extrapolating the horizontal line and the sharply rising portions of the UV-Vis absorption curves as can be seen in Fig. 4 and 5 also have been reported by Wong and Xu (2004). The absorption of undoped ZnO films at 500°C, at 5% Sn at 400°C and 600°C for 10 and 15% Sn were higher than those of the others for each temperature.…”

Problem statement:The focus of this research is to discover the significant influences of substituting low concentration Sn at Zn-site as an Anti-Reflecting Coating (ARC) for Zn 1-x Sn x O compound. The effects of tin dopants on the structural and morphology properties of ZnO thin films prepared using the sol-gel method were investigated. Approach: The effects of annealing temperature on the deposited films were also investigated at three different temperatures of 400, 500 and 600°C. The composition of the Zn 1-x Sn x O sample are x = 0.00, 0.05, 0.10 and 0.15. As a starting material, zinc acetate dehydrate was used; 2-methoxyethanol and mono ethanolamine were used as solvent and stabilizer, respectively. The dopant source was tin chloride. Results: Microstructural and surface morphology of samples were characterized by using Scanning Electron Microscopy (SEM). The crystallinity and defects are studied using X-Ray Diffraction (XRD). Molecular bonding is carried out using Raman spectroscopy and optical study of band gap is investigated using UV-VIS measurement. Conclusion:The value of band gap obtained increased slightly as the concentration of Sn increased. The increment of the band gap is acceptable as a requirement for good anti-reflecting coating element. Therefore these films can be applied on silicon solar cell.

“…Each catalyst exhibited a uniform crystal phase composition as Zn 2 TiO 4 (JCPDS or Zn 2 SnO 4 (JCPDS 24-1470), belonging to a typical inverted spinel-like structure. 29 The magnified image in Figure 1b shows that the XRD diffraction peaks attributed to the (3 1 1) crystal plane of S1). Obviously, with the increase of Zn 2 SnO 4 content, the unit cell parameter and unit cell volume of Zn 2 Sn x Ti 1−x O 4 solid solution were increased.…”

“…The only phase identified in the X-ray diffraction (XRD) patterns throughout the Zn 2 Sn x Ti 1– x O 4 samples is displayed in Figure a. Each catalyst exhibited a uniform crystal phase composition as Zn 2 TiO 4 (JCPDS 25-1164) or Zn 2 SnO 4 (JCPDS 24-1470), belonging to a typical inverted spinel-like structure . The magnified image in Figure b shows that the XRD diffraction peaks attributed to the (3 1 1) crystal plane of the Zn 2 Sn x Ti 1– x O 4 solid solution shift to lower diffraction angles with the increase in the Zn 2 SnO 4 content.…”

Solid-solution materials exhibit promising photocatalytic performance for complete photocatalytic conversion of carbon dioxide (CO2) and water (H2O) into solar fuels and oxygen (O2). In this study, Zn2Sn x Ti1–x O4 (0 ≤ x ≤ 1) solid-solution photocatalysts with an inverse spinel structure were prepared using the molten-salt-assisted method. The Zn2Sn x Ti1–x O4 solid-solution photocatalyst effectively enhanced CO2 photoreduction due to the increase in optical excitation centers, including SnO4 tetrahedrons, ZnO6, and TiO6 octahedrons. Numerous photoexcited centers generated sufficient photogenerated carriers to increase the overall redox reaction rate of H2O and CO2. In situ Fourier transform infrared spectroscopy analysis revealed that the distortion of the structural unit of the Zn2Sn x Ti1–x O4 solid solution not only improved the separation of photogenerated charges but also promoted the activation of CO2 molecules on the catalyst surface. Moreover, the reduction in the effective mass of photogenerated carriers in the Zn2Sn x Ti1–x O4 solid solution enables their fast migration, which results in excellent carrier movement. This synergistic effect leads to enhanced photoactivity of Zn2Sn x Ti1–x O4 for CO2 reduction.

The performance of nanocomposites semiconducting material used as a sensor is very much depending upon physical and chemical properties of the material. In this paper we address sensitivity of ZnSnO3thin film deposited by hydrothermal deposition in terms of its behavior towards humidity variations. The electrical, optical and structural properties of ZnSnO3thin film deposit at different volume of solvent (50 ml and 70 ml) grown by novel deposition of ZnSnO3hydrothermal with low temperature 95°C are also reviewed. The sensor performance of ZnSnO3thin film prepared at 50 ml volume show high sensitivity towards humidity. Using FESEM it was noted that the nanocube of ZnSnO3thin films growth on ZnO template with the size of nanocube is 100 to 140nm by varying the volume of the solvent.
