Structural characterization of zinc stannate thin films

Journal of Applied Physics, 2002
Polycrystalline thin films of Zn2SnO4 were deposited by rf magnetron sputtering onto glass substrates. Films were characterized by θ–2θ x-ray diffraction and by Sn119 conversion electron Mössbauer spectroscopy. The films were randomly oriented in a cubic spinel structure. Comparison of x-ray diffraction peak intensities with structure-factor-calculated

Zinc stannate flakes for optoelectronic and antibacterial applications

AIP Conference Proceedings, 2019
In this work we investigated the antibacterial application of zinc stannate grown using hydrothermal method at relatively low temperature of 100 °C. A systematic study was conducted by varying the molarity, pH and Zn/Sn ratio of the precursor solution, to obtain phase pure zinc stannate in one of its form, ZnSnO3.

Photocatalytic activity of zinc stannate: Preparation and modeling

Journal of the Taiwan Institute of Chemical Engineers, 2016
Abstract Zn 2 SnO 4 particles with the cubic shape are prepared via a two-step process, including co-precipitation and high-temperature solid state reaction procedures. The prepared photocatalyst has been characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), UV–vis diffuse reflectance spectroscopy and Fourier transform ...

Photocatalysis and luminescence properties of zinc stannate oxides

Ceramics International, 2017
Abstract In the present study, ZnO/SnO 2 nanocomposites and Zn 2 SnO 4 powder phosphors were synthesized via a sol–gel method through the control of annealing process. The coupled oxides ZnO/SnO 2 nanopowders formed after annealing at 400–600 °C, and the spinel zinc stannate phase appeared at 700 °C.

The influence of mechanical activation on zinc stannate spinel formation

Journal of the European Ceramic Society, 2001
Abstract Mechanical activation of inorganic materials leads to specific changes of their chemical and physical properties. Grinding, as one way of mechanical activation, is a widely used method for obtaining highly dispersed systems, and it could be performed in various types of mills (planetary, centrifugal, vibro-mill, etc.).

Al-doped zinc stannate films for photovoltaic applications

Korean Journal of Chemical Engineering, 2020
Al-doped zinc stannate (Zn2SnO4: Al or Zn-Sn-O: Al or AZTO) has attracted considerable attention as a next-generation transparent conducting oxide (TCO) owing to its properties. In this study, AZTO films were deposited by co-sputtering Al-doped zinc oxide (AZO) and SnO2 targets at room temperature.

Investigations of diffusion behaviour in Al-doped zinc oxide and zinc stannate coatings

Thin Solid Films, 2011
Abstract Multi-layer dielectric/silver/dielectric coating systems have excellent proprieties as heat insulators and for solar energy reflection and electrical conductivity. The largest market is dominated by low-emissivity (low-E) coatings, which are applied to large area architectural glazing to reduce heat losses from buildings.

Phase investigation and crystal structure analysis of zinc stannate (Zn2SnO4)

Physics Letters A, 2020
Abstract The space group of zinc stannate (Zn2SnO4) synthesized by one-pot hydrothermal method was often thought to be Fd3m. However, we observed the presence of (200) and (420) diffraction planes via X-ray diffraction and selected area electron diffraction patterns which are forbidden in Fd3m but allowed in F 4 ¯ 3m.

Single crystalline zinc stannate nanoparticles for efficient photo-electrochemical devices

Chemical Communications, 2010
Single crystalline zinc stannate (Zn(2)SnO(4) and ZnSnO(3)) nanoparticles were synthesized by a simple one-step hydrothermal reaction with a high production yield. Zn(2)SnO(4) is a (111) face-exposed octahedron, whereas ZnSnO(3) is a (100) face-exposed hexahedron structure.
