In this work, (CdO)1-x (CoO)x thin films were prepared on glass slides by laser-induced plasma using Nd:YAG laser with (λ=1064 nm) and duration (9 ns) at different laser energies (200-500 mJ) with ratio (x=0.5), The influence of laser energy on structural and optical properties has been studied. XRD patterns show the films have a structure of polycrystalline wurtzite. As for AFM tests results for the topography of the surface of the film, where the results showed that the grain size and the average roughness increase with increasing laser energy. The optical properties of all films were also studied and the results showed that the absorption coefficient for within the wavelength range (280-1100 nm), The value of the optical power gap for direct transitions was shown to be reduced by increasing laser energy within the range (4.29-3.7 eV).

“…In the previous experiment, when the oxygen flow rate increased from 2 sccm to 10 sccm, the oxides changed from Cu2O, Cu4O3 to CuO, respectively [12][13][14]. During the preparation of copper alloy oxide, the ratio of argon to oxygen was controlled by 50:2, 50:4, 50:6, 50:8 and 50:10.…”

In order to identify new selective infrared radiative materials, Cu80Ni15Ag5 and Cu70Ni25Ag5 oxides were prepared by DC reactive magnetron sputtering under atmosphere with different ratio of argon to oxygen. The composition of the copper alloy oxides was analyzed by XRD, XPS and Raman. When the ratio of argon to oxygen was 50:2, the alloy oxide is amorphous, whereas the alloy oxide prepared at the ratio of argon to oxygen from 50:4 to 50:10 is Cu4O3. The doping of Ni and Ag may impede CuO phase formation, deteriorate the crystallinity, and increase the defects. The emissivity measurement results show that Cu70Ni25Ag5 oxides prepared at the ratio of argon to oxygen of 50:10 have good selective infrared radiative properties, and the emissivity difference is more than 0.8 between 3μm band and 8-14μm band.

“…Phase-mixture problems can be overcome by controlling oxygen flow. In situ plasma diagnosis was performed to study the sputtering mechanism, and it was found that the phase transition from Cu 2 O to CuO is governed by oxygen density in reactive magnetron sputtering [ 23 ]. The oxygen density tunes the oxidation state of the final metal-oxide thin film.…”

“…According to the authors, as the oxygen pressure increased, a granular surface with higher porosity was achieved [ 25 ]. Accordingly, the authors reported high gas-sensing capabilities of NiO towards hydrogen due to the porous structure, providing a high adsorption rate [ 23 ]. One of the benefits of reactive magnetron sputtering is that it permits growth at room temperature without the need for additional annealing.…”

This review focuses on the synthesis of p-type metal-oxide (p-type MOX) semiconductor thin films, such as CuO, NiO, Co3O4, and Cr2O3, used for chemical-sensing applications. P-type MOX thin films exhibit several advantages over n-type MOX, including a higher catalytic effect, low humidity dependence, and improved recovery speed. However, the sensing performance of CuO, NiO, Co3O4, and Cr2O3 thin films is strongly related to the intrinsic physicochemical properties of the material and the thickness of these MOX thin films. The latter is heavily dependent on synthesis techniques. Many techniques used for growing p-MOX thin films are reviewed herein. Physical vapor-deposition techniques (PVD), such as magnetron sputtering, thermal evaporation, thermal oxidation, and molecular-beam epitaxial (MBE) growth were investigated, along with chemical vapor deposition (CVD). Liquid-phase routes, including sol–gel-assisted dip-and-spin coating, spray pyrolysis, and electrodeposition, are also discussed. A review of each technique, as well as factors that affect the physicochemical properties of p-type MOX thin films, such as morphology, crystallinity, defects, and grain size, is presented. The sensing mechanism describing the surface reaction of gases with MOX is also discussed. The sensing characteristics of CuO, NiO, Co3O4, and Cr2O3 thin films, including their response, sensor kinetics, stability, selectivity, and repeatability are reviewed. Different chemical compounds, including reducing gases (such as volatile organic compounds (VOCs), H2, and NH3) and oxidizing gases, such as CO2, NO2, and O3, were analyzed. Bulk doping, surface decoration, and heterostructures are some of the strategies for improving the sensing capabilities of the suggested pristine p-type MOX thin films. Future trends to overcome the challenges of p-type MOX thin-film chemical sensors are also presented.
