“…This would confirm the possibility of incorporation of the metal ions as a substituent in TiO 2 lattice. Consistently with the larger size of In 3+ (0.080 nm) (23) than Ti 4+ (0.0605 nm) (24) is increasing of the lattice parameters a and c (see Table 1) with increasing content of indium. In 3+ is likely to substitute for Ti 4+ in the anatase structure.…”

A novel In(3+)-doped TiO(2) and TiO(2)/In(2)S(3) nanocomposites for photocatalytic degradation of environmental pollutants and stoichiometric degradation of warfare agents were prepared by a homogeneous hydrolysis with urea and thioacetamide, respectively. The prepared samples series TiInTAA were annealed at 600°C. The prepared samples were characterized by X-ray powder diffraction, IR spectroscopy, Raman spectroscopy, specific surface area (BET) and porosity determination. The method of UV-Vis diffuse reflectance spectroscopy was employed to estimate band-gap energies. The photocatalytic activity (PCA) was tested by degradation of Orange dye, whereas stoichiometric activity was studied by degradation of sulfur mustard. Incorporation of In(3+) into titania lattice increases PCA of TiO(2) in the visible light and increases stoichiometric decomposition of sulfur mustard against nondoped TiO(2) as well. PCA of TiO(2)/In(2)S(3) composite depends on the optimal ratio of TiO(2):In(2)S(3) in composite, while the activity for stoichiometric decomposition of sulfur mustards depends on the content of In(2)S(3) in nanocomposite.

“…It is an attractive substitute to ITO since zinc and tin replace indium, which has become more expensive and scarce. Since the first literature report of ZITO in 1995 [33] many studies on the properties, range of compositions, and defects have been published [34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49]. N-type bixbyite ZITO materials having more tin than zinc exhibit electrical properties comparable to ITO.…”

Transparent conducting oxide (TCO) materials are implemented into a wide variety of commercial devices because they possess a unique combination of high optical transparency and high electrical conductivity. Created during the processing of the TCOs, defects within the atomic-scale structure are responsible for their desirable optical and electrical properties. Therefore, studying the defect structure is essential to a better understanding of the behavior of transparent conductors. X-ray and neutron scattering techniques are powerful tools to investigate the atomic lattice structural defects in these materials. This review paper presents some of the current developments in the study of structural defects in n-type TCOs using x-ray diffraction (XRD), neutron diffraction, extended x-ray absorption fine structure (EXAFS), pair distribution functions (PDFs), and x-ray fluorescence (XRF).

“…6,7 No appropriate donor-dopant for SnO 2 exists in the ZnO-In 2 O 3 -SnO 2 system, but SnO 2 is the most used TCO (by sheer volume, as a low emissivity coating on architectural glass), exhibiting conductivities as high as 9000 S/cm (when doped by F). 8 There is one binary compound in the ZnO-SnO 2 system, namely the ZnSn 2 O 4 spinel, 9 and at least seven ''homologous series'' compounds in the ZnO-In 2 O 3 system at the temperature of interest (12751C), whose formula is (ZnO) k Á In 2 O 3 (k 5 3, 4, 5, 6, 7, 9, 11). 10 The zinc stannate spinel can be rendered moderately conductive by In 2 O 3 doping.…”

The subsolidus phase relationships in the ZnO–InO1.5–SnO2 system were investigated at 1275°C using X‐ray diffraction. Each of the end members of the ternary diagram is a transparent conducting oxide. There are two substantial solid solutions in the ternary phase space, the bixbyite solid solution In2−2xZnxSnxO3 (x=0–0.40), and the indium substituted zinc stannate spinel, Zn(2−x)Sn(1−x)In2xO4 (x=0–0.45). The bixbyite solid solution is an outstanding TCO, whereas the spinel is only moderately conducting. Along the ZnO–InO1.5 binary, there is a series of transparent conducting homologous compounds (ZnO)k·In2O3 (where k=3, 4, 5, 6, 7, 9, 11). Within ternary phase space, these homologous compounds were found to exhibit negligible Sn solubility, and were always found to be compatible with the spinel. Equilibrium was difficult to achieve in the phase space between the homologous series compounds and the spinel, owing to sluggish kinetics. A procedure involving mixtures of prereacted spinel and the Zn11In2O14 (k=11) compound was developed, which allowed for more rapid approach to thermodynamic equilibrium, thereby allowing for the establishment of phase relationships near the ZnO corner of the phase diagram.
