“…The band gap was estimated by extrapolating (αhυ) 2 = 0 to give a straight line. As clearly seen in Figure b, the optical band energy gap was 2.0 eV with (αhυ) 2 versus hυ for an indirect allowed transition for β-Cu 2 O NPs . The band gap energy ( E g ) may vary with the type of transition up to 0.5 eV for the same semiconductor.…”

The physicochemical approaches and biological principles in bio-nanotechnology favor specially functionalized nanosized particles. Cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase with a little tenorite (CuO) may be very effective in the development of novel therapeutic approaches against several fatalities including A-549 lung carcinoma cell lines. Consequently, the synthesis of β-Cu2O NPs for the improvement in the therapeutic index and drug delivery application is becoming an effective strategy in conventional anticarcinoma treatment. Hence, surface-enhanced nanosized spherical cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase were successfully prepared using poly(ethylene glycol) (PEG) as an amphiphilic nonionic surfactant and l-ascorbic acid (K3[Cu(Cl5)]@LAA-PEG) reduced to cuprites β-Cu2O NPs via the sonochemical route. Less improved toxicity and better solubility of β-Cu2O NPs compared with Axitinib were a major reason for producing β-Cu2O NPs from K3[Cu(Cl5)]@LAA-PEG (LAA, l-ascorbic acid, PEG, poly(ethylene glycol) (PEG)). These nanoparticle syntheses have been suggested to influence their cytotoxicity, free-radical scavenging analysis, and reactive oxygen species (ROS) using poly(ethylene glycol) (PEG) and l-ascorbic acid (LAA) as coated and grafted materials due to their dose-dependent nature and IC50 calculations. The surface morphology of the formed β-Cu2O NPs has been examined via UV–vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy with energy diffraction scattering spectroscopy (SEM@EDS), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) analysis. X-ray diffraction (XRD) and Brunauer–Emmett–Teller (BET) surface analysis results confirm the presence of pure cuprite with a very little amount of tenorite (CuO) phase, Dynamic light scattering (DLS) confirms the negative ζ-value with stable nature. Docking was performed using PDB of lung carcinomas and others, as rigid receptors, whereas the β-Cu2O NP cluster was treated as a flexible ligand.

“…Electrochemically synthesized metallic copper or copper oxide layers are widely used as functional materials, such as for through-hole deposition technology in printed circuit boards (PCBs) [1,2], 3D printing [3], and sensor devices [4,5], due to their excellent physical properties and cost performance. Among them, electrodeposited metallic copper layers or multilayers have been extensively studied with respect to their additives [6,7], multilayered structure [8][9][10] and mechanical properties [11,12].…”

Nanocrystalline thick copper films with the thickness of ∼250 μm were electrochemically synthesized from an acidic aqueous solution containing polyethylene glycol (PEG) with the average molecular weight of 3,000 to investigate the preferential crystal orientation and mechanical properties such as microhardness and tensile strength. By addition of PEG to the electrolytic bath, the cathode potential was shifted to a less noble direction during the electrodeposition and the average crystallite size of electrodeposited copper thick films was decreased. The copper thick films electrodeposited from the solution without PEG exhibited a preferentially orientation in (220) texture while that obtained from the solution containing PEG was composed of nanocrystals with random crystal orientation that containing (111) and (200) textures. The micro-Vickers hardness, tensile strength, and elongation of the electrodeposited copper thick films reached up to 133 HV, 234 MPa, and 13.1%, respectively. These improvements in mechanical properties can be explained by the grain refinement effect and the random crystal orientation effect.

“…Different techniques are utilized for the deposition of Cu 2 O thin films, including pulsed laser, copper foil oxidation within a thermal technique, chemical bath deposition, electrodeposition, spin coating, and radio frequency (RF) sputtering. Films prepared using RF techniques are characterized by low imperfections, favorable homogeneity, in addition to good coherent and adherent properties [16][17][18]. It is widely utilized in numerous scientific applications, including gas sensors, biosensors, supercapacitors, lithium-ion batteries, photocatalytic dye removal, solar cells, and photoelectrochemical water splitting [19][20][21][22][23][24].…”

High Performance of Nanostructured Cu2O-Based Photodetectors Grown on a Ti/Mo Metallic Substrate

et al. 2023

In this work, cuprous oxide (Cu2O) thin films were prepared using a simplistic sputtering technique. The films were grown on both traditional fluorine-doped tin oxide (FTO) and Ti-metallic substrates. X-ray diffraction applied for investigation of the crystal structure proved that the Cu2O layer acquires the cubic structure with a (111) main peak at 2θ of 36.46°. The optical absorption and transmission were detected through the utilization of a UV-Vis spectrophotometer, and the optical bandgap for the Cu2O layer was determined to be ~2.15 eV using Tauc’s equation. XPS and scanning electron microscopy were also performed for chemical structure and morphological investigation, respectively. The optoelectronic behaviors for the prepared samples were carried out using a Keithley source meter; the photocurrent density was measured in a range of applied voltage between −1 and 1 volt under the illumination of a xenon lamp with a power density of 100 mWcm−2. External quantum efficiency, sensitivity, responsivity, and detectivity were computed using proprietary models based on the experimental data.
