“…The peak at 520 cm À1 was attributed to the Si substrate, and that at 665 cm À1 to the ZTO phase. 27,34,37 No Raman modes of other phases such as ZnO, SnO 2 or SnO were observed. Samples were of a highly pure single phase.…”

“…35 They exhibited morphologies resembling necklaces of rhombohedra, and their periodic axial surface structure was similar to a previous report. 34 The morphology of ZTO:Mn samples in Figs. 1(b) and 1(c) was similar to that of undoped ZTO in Fig.…”

“…[30][31][32] Numerous experimental and theoretical studies have investigated the structural, electrical, and optical properties of ZTO. 27,33,34 The magnetic properties of TM-doped ZTO have received far less attention, and the mechanism of magnetism in ternary oxides may differ from that in binary oxides. Mn is an attractive TM-dopant because of its d 5 electron configuration and large magnetic moment.…”

“…These materials have been thoroughly investigated and employed in many applications. However, ternary oxide TCOs such as Zn 2 SnO 4 [1], CdIn 2 O 4 [2], ZnGa 2 O 4 [3] and Cd 2 SnO 4 [4] have eminent properties required for a transparent conducting oxide (TCO). Amongst these TCOs, n-type ternary Cd 2 SnO 4 thin films show low electrical resistivity (10 −4 cm), high transmission (>90%) in the visible region and smoother surfaces than conventional SnO 2 TCO films [5,6].…”

Thermal and optical properties of Cd2SnO4 thin films using photoacoustic spectroscopy

Cadmium stannate (Cd 2 SnO 4 ) thin films were prepared by the RF magnetron sputtering technique on glass substrates with substrate temperatures of room temperature (RT), 100°C, 200°C and 300°C. Photoacoustic analyses were made to obtain the thermal diffusivity and the optical bandgap values of the Cd 2 SnO 4 thin films. The change in thermal diffusivity of the films with the substrate temperature was analyzed. The optical bandgap values obtained from the photoacoustic spectroscopy were compared with the values obtained from the optical transmittance spectra. X-ray photoelectron spectroscopic (XPS) studies confirm the formation of stoichiometric films. Surface morphological studies by atomic force microscopy (AFM) revealed the crystalline nature of the films deposited at 100°C.

Twinned Zn₂TiO₄ Spinel Nanowires Using ZnO Nanowires as a Template

One-dimensional (1D) semiconductor metal oxide nanostructures, such as nanowires, nanobelts, and nanotubes, have attracted considerable attention due to their prominent electrical, optical, and chemical properties and potential applications in nanoscale electronic and optoelectronic devices. [1][2][3][4][5] However, the properties and applications of those nanomaterials are limited by their simple binary systems.[6] Therefore, synthesis of complex functional nanomaterials with controlled size and morphology, such as core/shell quantum dots, [7] nanowires and nanobelts, [8][9][10][11] heterostructures, [6,12] superlattices, [13] and nanotubes, [14][15][16] are highly desirable. Furthermore, 1Dternary nanocomposites, such as Zn 2 SnO 4 , [8][9][10]17] Zn 2 TiO 4 , [18] ZnGa 2 O 4 , [11,16] MgAl 2 O 4 , [14] CoFe 2 O 4 , [19] exhibit specific functions that are unattainable by common binary composites. Conventional synthesis methods of those ternary composites usually involve high-energy ball milling of two binary solid oxides [18] or a high-temperature solid reaction, [20,21] which are not suitable for 1D nanostructure growth. Only recently, syntheses of single-crystal ternary oxide nanowires and nanotubes have been achieved by using Ga 2 O 3 , MgO, or ZnO nanowires as template. [11,14,15] For face-centered cubic (fcc) nanostructures, twinning is probably the most common structural defect, especially in metal and metal alloy nanoparticles, [22,23] where two subcrystallites share a facet to form a mirror image of each other. Twinning is occasionally observed in binary systems, such as cubic ZnS and InP nanowires, [24,25] both of which have a preferential <111> growth direction. However, reports on the synthesis of twinned structures of fcc ternary nanowires are rare; [10] that is, the formation of twinned nanowires has yet to be revealed.Zinc titanate (Zn 2 TiO 4 ) is an inverse spinel, which has been used as a catalyst and pigment in industry. It is one of the leading regenerable catalysts and has been demonstrated to be a good sorbent for removing sulfur-related compounds at high temperature. [26,27] As a dielectric material, its physical, electrical, and optical properties have been studied for various applications. [21,28,29] In this Communication, we shall demonstrate a three-stage synthesis of twinned Zn 2 TiO 4 nanowires using ZnO nanowires as template, which could be further developed for controlled synthesis of ternary oxide nanostructures. Figure 1a-c shows the scanning electron microscopy (SEM) images of ZnO nanowires and ZnO/Ti core/shell nanowires before and after annealing, respectively. The as-grown ZnO nanowires shown in Figure 1a are randomly aligned, of about 40-60 nm in diameter, and 10 lm in length. It can be seen clearly that the morphology of the ZnO nanowires is reserved after coating with Ti (Fig. 1b). The surface is smooth and the diameter of the Ti-coated nanowires is increased to 70-100 nm. No aggregated Ti particles could be seen in Figure 1b, indicating a uniform deposition of Ti on ZnO ...
