The synergistic effect of bimetallic co‐incorporated metal oxides have gained enormous attention due to their unique optoelectronic properties. Herein, we present the green synthesis of ZnO, Cu‐incorporated ZnO, Mn‐incorporated ZnO, and Cu‐Mn co‐incorporated nanoparticles (ZnO NPs, CuZnO NPs, MnZnO NPs, MnCuZnO NPs) for antimicrobial and photocatalytic reduction applications using corn silk extract and industrial metal wastes. The as‐synthesized NPs were characterized by using UV‐visible absorption spectroscopy (UV‐Vis), photoluminescence (PL) spectroscopy, Fourier‐transformed infrared spectroscopy (FT‐IR), powdered x‐ray diffraction (XRD), and scanning electron microscopy (SEM). CuZnO, MnZnO, and MnCuZnO NPs efficiently inhibited bacterial culture growth. The photocatalytic reduction activity of as‐synthesized NPs against the different concentrations of 4‐nitrophenol (4‐NP) in water was also investigated. CuZnO and MnCuZnO nanoparticles were to be efficient photocatalysts for reducing 4‐NP into 4‐aminophenol (4‐AP).Research Highlights Green synthesis of nanomaterials by agricultural and industrial wastes Cu and Mn co‐incorporated ZnO NPs have shown good photocatalysis and antimicrobial activities Green approach for waste conversion to value‐added products

“…Two studies featuring identical SILAR fabrication strategies conducted by the same research group attempted individual and combined doping of CdO using cadmium acetate in an aqueous ammonia solution as the cationic precursor (pH ≈ 12), and the desired dopant was added into the cationic precursor in the of the metal salt (i.e., Al(NO 3 ) 3 , CoCl 2 , MnCl 2 , and CuCl 2 ). [239,240] The as-deposited coatings, both doped and undoped were all annealed at 350 °C for 45 min. Dopantinduced grain size increase was observed in all CdO films suggesting a role of the dopant in affecting crystal growth.…”

“…In the case of Mn and Cu doping, the highest crystallite size (≈20 nm) was observed for 1% Mn and 0.5% Cu co-doped CdO sample while bandgaps of all individual and co-doped systems of Mn and Cu exhibited grater bandgaps than the undoped CdO (2.08 eV) implying the positive effect of the large bandgap of MnO (4.2 eV) on the overall bandgap of the doped CdO system. [240] However, in neither studies the electrical properties were reported, making it difficult to assess the use of these coatings as transparent electrodes.…”

Methods for the fabrication of thin films with well controlled structure and properties are of great importance for the development of functional devices for a large range of applications. SILAR, the acronym for Successive Ionic Layer Adsorption and Reaction, is an evolution and combination of two other deposition methods, the Atomic Layer Deposition and Chemical Bath Deposition. Due to a relative simplicity and low cost, this method has gained increasing interest in the scientific community. There are, however, several aspects related to the influence of the many parameters involved, which deserve further deepening. In this review article, the basis of the method, its application to the fabrication of thin films, the importance of experimental parameters, and some recent advances in the application of oxide films are reviewed. At first the fundamental theoretical bases and experimental concepts of SILAR are discussed. Then, the fabrication of chalcogenides and metal oxides is reviewed, with special emphasis to metal oxides, trying to extract general information on the effect of experimental parameters on structural, morphological and functional properties. Finally, recent advances in the application of oxide films prepared by SILAR are described, focusing on supercapacitors, transparent electrodes, solar cells, and photoelectrochemical devices.

“…CdO has a cubic (NaCl) structure based on octahedral coordination around Cd atoms and an Fm-3m symmetry with = 4.695 ̇ (Dakhel 2014a;Dakhel and Bououdina 2014;Sahare, et al 2017). These suitable physical properties have helped CdO thin films to have applications in photovoltaic solar cells, optoelectronic devices, smart windows, panel displays, thermally insulating glass, gas sensor devices, transparent electrodes, photodiodes, liquid crystal displays, IR detectors, and anti-reflection coatings, to name but a few (Aydin, et al 2019;Dakhel and Bououdina 2015;Elttayef, et al 2013). However, the optoelectronic properties of CdO thin films need to be adjusted and tailored for many optoelectronic applications.…”

In this study, the pure and Cu doped CdO thin films with various doping concentrations (0 to 5 at.%) were deposited on soda-lime glass substrates, using the chemical spray pyrolysis technique. The effects of Cu doping on the structural, optical, and electrical properties of thin films were, then, investigated. The films were characterized through X-ray diffraction (XRD), field emission scanning electron microscopy equipped with an energy dispersive x-ray analyzer (FESEM-EDX), atomic force microscopy (AFM), ultraviolet-visible spectroscopy, and electrical resistance; van der Pauw techniques were also used to measure the Hall effect. X-ray diffraction studies showed that the thin films were polycrystalline only with cadmium oxide phase with the cubic face-centered crystal structure and the preferred orientations were along (111), (200), (220), (311), and (311) planes. The FE-SEM and AFM images also showed that with an increase in Cu doping levels, the grain size and surface roughness of the thin films decreased from 472 to 38 nm and from 163 to 54 nm, respectively. The expected element compositions were confirmed by EDX. The optical bandgap of the thin films ranged from 2.42 to 2.56 eV, and as Cu dopant increased, so, too, the optical bandgap. As the Cu doping concentration increased from 0 to 5 (at.%), the electrical resistivity and Seebeck coefficient were found to increase from 3.74⋅10− 4 to 8.77⋅10− 3 Ω.cm and 8.28⋅10− 6 to 2.52⋅10− 5 v/k (at 100 Co temperature difference), respectively; the carrier concentration and carrier mobility were also found to decrease from 3.24⋅1020 to 1.76⋅1020 cm− 3 and from 55.5 to 4.05 cm2/v.s, respectively. The Hall effect and thermoelectric studies revealed that the films exhibited an n-type conductivity.
