“…The shape of the grains changes from spherical and elliptical at 10 % copper oxide to spherical at 20 % copper oxide, due to the nanocomposite formation of the mixed films, as shown in figure 2. This behavior corresponds to the XRD result and an agreement with that described by Suhai et al [5] and Sofi et al [17].…”

An NH3 gas sensor was prepared from nanocomposite films of indium oxide-copper oxide mixtures with ratios of 0 , 10 , and 20 Vol % of copper oxide. The films were deposited on a glass substrate using chemical spray pyrolysis method (CSP) at 400oC. The structural properties were studied by using X-ray diffraction (XRD) and atomic force microscopy ( AFM). The structural results showed that the prepared thin films are polycrystalline, with nano grain size. By mixing copper oxide with indium oxide, the grain size of the prepared thin films was decreased and the surface roughness was increased. The UV-Visible spectrometer analysis showed that the prepared thin films have high transmittance. This transmittance was decreased by mixing copper oxide with indium oxide. The direct optical energy gap ranged 3.5 - 3 eV, which was decreased with increasing copper oxide concentration. The sensitivity of the prepared gas sensor was measured towards NH3 gas at a concentration of 71ppm with operating temperatures of 100, 150, 200, 250 and 30) oC, according to the change of sensor resistance. This sensitivity of the mixture oxides showed a value of about nine times greater than that of individual indium oxide thin films. The results of the optimum gas sensor properties demonstrated a sensitivity value of 75.06%, response time of 10s, and recovery time of 11 s, at a mixing ratio of 20% of copper oxide and an operating temperature of 200oC.

In this article, the structural, optical, and electrical properties of Indium Tin Oxide (ITO) films deposited at different plasma powers were investigated. The transmittance values in the visible region were measured, revealing that the ITO film deposited at 2050 W exhibited the highest transmittance (81%). Additionally, the sheet resistance values of all films were analyzed, indicating that the ITO film deposited at 2050 W had the lowest sheet resistance (64.9 Ω/sq). Through XRD analysis, the structural properties of the films were examined, and the diffraction peaks of the ITO films were identified. Notably, the ITO film deposited at 2050 W demonstrated superior performance compared to the other films deposited using various plasma powers. Finally, we report a noteworthy efficiency of 17.03% achieved in the SHJ solar cell fabricated with the ITO film deposited at 2050 W on a 5x5 cm2 n-type Si substrate.

“…where D is the mean crystallite size in nm. Sofi et al [17] observed the doping concentration grew from 0 to 7 %, and dislocation density values of a declining trend order indicated a shift in disorder in Cu doped In2O3 through the citrate gel process. And through the solidstate reaction process also observed an increase in dislocation density in the prepared indium-rich samples and a decrease in the dislocation density in the copper-rich sample.…”

Copper Indium Oxide (CuInO2) nanocrystalline powder samples with different Cu/In ratios were prepared using the conventional solid-state reaction method. The structural, morphological, and optical properties of CuInO2 samples were studied. The delafossite structure of copper indium oxide nanocrystalline samples with (0 1 2) preferential orientation is observed. With altering the composition, the particles size of the prepared powder samples changed ranging from 6 nm to 94 nm, and the energy band gaps varied from 2.20 eV to 2.37 eV. Photoluminescence intensity at 595 nm and 596 nm in the visible region enhanced with variation of Cu/In ratios.
