“…No conspicuous pinnacle shift rela ted to Cu2O phase or recognizable impurities were identified with an increment in the annealing temperature. It can be deduced from the XRD patterns that annealing improves the crystallinity and the purity of the CuO formation process [24]. The crystallite size"( ave D ) is calculated using Scherrer's relation, and the dislocation density"(δ) was obtained using Eq.…”

 The chemical bath deposited method was used because its simple, easy, and inexpensive.  A rod-like nano-structure of Copper Oxide was prepared.  The effect of annealing temperature (400 and 500) was studied.In this paper, we reported that the annealing at temperatures of 400 and 500 oC in the air for 2 hours led to the formation of rod-like structures of cupric oxide thin films prepared by the chemical bath deposition technique. The structure and the optical properties of the prepared thin films were studied to investigate the role of annealing on the films. The morphology of the as-deposited CuO films is almost structureless. However, the films are converted to rod-like shapes nanostructures after annealing, as confirmed by scanning electron microscopy. The xray analysis showed that the thin films of copper oxide nano-structures have a monoclinic crystallinity preferred in the ( 110), (002), and ( 111) directions, and the crystallinity increases after annealing. Furthermore, the bandgap values after annealing are reduced from 2.1 to 1.61 and 1.63 eV as determined by optical analysis utilizing UV-VIS spectroscopy.

“…In this study, FeO thin films were synthesized through the Sequential Ionic Layer Adsorption and Reaction (SILAR) technique. The amperometric approach was subsequently employed to examine the presence of azo dyes AR and DB15 within food samples [14]. The findings present promising prospects for the development of devices tailored for the rapid detection of toxic azo dyes in liquid samples using FeO thin films.…”

This study reports on the amperometric sensing properties of FeO/Fe2O3 thin films for the detection of Allura Red (AR) and Direct Blue 15 (DB15) Azo dyes. The FeO/Fe2O3 thin films were produced using the Sequential Ionic Layer Adsorption and Reaction (SILAR) method and Na+-doping. The morphological and structural properties of the nanocomposites produced at pH of 10.5 showed good properties for the detection of azo dyes. The linear curve fit equations for AR and DB15 droplet applications onto Na+-doped FeO nanocomposite thin film samples were found to be y = -0.0002x + 0.0043 (R² = 0.9143) and y = -7E-05x + 0.0005 (R² = 0.9809), respectively. The findings reveal that adding Na+ doping to FeO/Fe2O3 thin films can effectively increase the detection response for the target azo dyes and enhance the sensitivity of the sensing system. The results suggest that the SILAR method can be used to produce low-cost and reusable FeO/Fe2O3 thin film devices, which can be promising candidates for the detection of toxic azo dyes in liquid samples.
