“…It is observed from this table that ZTO600 sample have the small value of electrical resistivity and hence largest FOM value (∼0.11 Ω −1 ) to make it suitable for TCO applications. These values are four orders of magnitude greater than that reported for similar compositions (10 -5 Ω −1 ) by Bibi et al [35].…”

In the present work, the effect of annealing temperature on structural, optical and electrical properties for sol gel synthesized Zn 2 SnO 4 nanostructured films has been investigated for their suitability in optoelectronics. These samples were probed by using XRD, UV-Visible spectroscopy, photoluminescence spectroscopy and Hall measurements. The x-ray diffraction study divulges the polycrystalline nature and phase transition from cubic inverse spinal Zn 2 SnO 4 phase to pervoskite ZnSnO 3 phase in the synthesized films. The optical transmission of ∼43 %-73 % in the visible region while the optical gap varies from 3.61-3.95 eV has been observed for the annealed films. The defect related emission peaks at 423, 445 and 481 nm has been observed. The lowest electrical resistivity (5.8×10 -3 Ωcm) and highest figure of merit (10 -3 Ω −1 ) for the films annealed at 600°C has been observed. These results are very important for the development of new n-type transparent conductor for various optoelectronic devices.

“…[23] The bandgaps of pure ZnO and SnO 2 are 3.26 and 3.91 eV, respectively; the optical bandgaps of ZnSnO films are between the bandgaps of ZnO and SnO 2 , which is in line with the results obtained by other researchers. [27] Figure 7 shows the photoluminescence (PL) spectra of the ZnSnO films which are recorded using He-Cd laser (325 nm) as excitation source. The ultraviolet emission at 379 nm originates from the recombination of electrons and holes at the band edges of ZnO, while the peak at 758 nm is the secondary UV diffraction.…”

ZnO and SnO 2 are two important wide bandgap semiconductor materials, which have applications in many fields. [1][2][3][4][5][6] In order to tailor the properties of ZnO and SnO 2 , Sn-doped ZnO and Zn-doped SnO 2 have been studied. [7][8][9][10] Recently, nanocomposites composed of ZnO and SnO 2 and ternary compounds composed of Zn, Sn, and O have also attracted wide attention from scholars and engineers in different fields. For instance, Lee et al. [11] used pulsed laser deposition to prepare ZnO-SnO 2 composite films; those composite films were amorphous after annealed at 300 C but had good photoelectric properties and could be used to prepare high-quality field effect transistors. T. Tharsika et al. [12] used spray pyrolysis technique to prepare a ZnO-SnO 2 composite film and found that the morphology of the sample was controlled by the heat treatment and the Zn:Sn ratio in the growth solution. Yan et al. [13] prepared ZnO/ZnSnO 3 composites by hydrothermal method and found that those composites had better gas sensitivity than pure ZnSnO 3 . Zheng et al. [14] synthesized a ZnO-SnO 2 nanocomposite through a two-step route and found that the sensor prepared from the composite material showed better gas sensitivity to chlorine than the sensor prepared from pure SnO 2 . The ZnO-SnO 2 nanocomposites and ternary compounds composed of Zn, Sn, and O have attracted great attention from researchers worldwide because they have potential applications in field effect transistors, [11] solar cells, [14,15] thin-film transistors, [16] gas sensors, [17,18] photocatalysts, [19] and other fields.As we all know, the preparation methods and deposition parameters of nanomaterials have a large influence on the properties of nanomaterials. For ZnSnO nanomaterials, the impact of different preparation methods is particularly obvious. Normally, the ZnSnO films obtained by the physical vapor method show smooth surface and uniform grains. [11,13] However, ZnSnO thin films deposited by the wet chemical method show higher controllability of morphology and optoelectronic properties. [20,21] For instance, Tharsika et al. [20] fabricated ZnO-SnO 2 composite films by spray pyrolysis; the microstructure and optical properties of the ZnO-SnO 2 films were not only related to the atomic ratio of Zn to Sn in growth solution, but also related to the heat-treatment temperature. The ZnO-SnO 2 composite film heat-treated at an appropriate temperature showed a double-layered structure: The bottom layer was an amorphous Zn x Sn y O z compound, and the upper layer was made up by many rod-like or sheet-like ZnO nanostructures. The sol-gel process is an attractive way for preparing metal oxide nanofilms and is particularly suitable for preparing multicomponent metal oxide films. To our knowledge, up to present, there is no paper to report a two-layered film composed of crystalline ZnO and amorphous Zn x Sn y O z compound deposited using the sol-gel technique. In this research, the authors have prepared ZnSnO thin films with unique microstructure and optica...

“…In the past decades, ZnO has been widely studied because of its great potential in nano-device research [3][4][5]. ZnO has a 3.37 eV band gap and large exciton binding energy, which enables it to possess good physical and chemical properties [6]. It is a promising material for fabricating photodetectors, light-emitting diodes, solar cells and photocatalysts [7][8][9][10].…”

Preparation of ternary ZnO/Ag/cellulose and its enhanced photocatalytic degradation property on phenol and benzene in VOCs

et al. 2019

The ZnO/Ag/cellulose composite (ZAC) with excellent photocatalytic activity of degrading benzene and phenol in VOCs has been successfully synthesized. EDS, TEM, XPS and UV-vis analyses show that the ZAC is a ternary composite. It is composed of Ag, ZnO and cellulose, where the cellulose works as the substrate to anchor the other two components. The X-ray diffraction patterns find well-crystallized ZnO nanoparticles. Multiple PL peaks in the visible region measured for ZAC, imply rich defects on ZnO. It is observed that Ag nanoparticles are mainly attached on ZnO in the composite, which would raise the separation efficiency of photogenerated electrons and holes. Photocatalytic degradation shows that ZAC is able to decompose almost 100% phenol and 19% benzene in VOCs under UV light irradiation (6 W) which is almost no harm to human body. Due to the renewable cellulose, our ternary composite ZAC imparts low-cost, easily recycled and flexible merits, which might be applied in the indoor VOCs treatment.
