“…It is possible to tune the electronic states of local sites on crystal surfaces by a high‐energy ion beam or laser irradiation . Laser irradiation has been utilized for inducing oxygen deficiency into TiO 2 , CaTiO 3 , and Sm 0.5 Ba 0.5 MnO 3 and for phase or structural transformation of α‐Al 2 O 3 to γ‐Al 2 O 3 , α‐Bi 2 O 3 to δ‐Bi 2 O 3 , tetragonal Cu 4 O 3 to monoclinic CuO, orthorhombic WO 3 ·H 2 O to monoclinic WO 3 , orthorhombic to monoclinic to cubic ZrO 2 , and tetragonal SrCuO 2 to orthorhombic SrCuO 2 …”

Recent technological advances in developing a diverse range of lasers have opened new avenues in material processing. Laser processing of materials involves their exposure to rapid and localized energy, which creates conditions of electronic and thermodynamic nonequilibrium. The laser-induced heat can be localized in space and time, enabling excellent control over the manipulation of materials. Metal oxides are of significant interest for applications ranging from microelectronics to medicine. Numerous studies have investigated the synthesis, manipulation, and patterning of metal oxide films and nanostructures. Besides providing a brief overview on the principles governing the laser-material interactions, here, the ongoing efforts in laser irradiation of metal oxide films and nanostructures for a variety of applications are reviewed. Latest advances in laser-assisted processing of metal oxides are summarized.

“…The metal oxide nanoparticles are of particular interest as they exhibit unique phenomenal properties [14]. Copper is an abundantly available multivalent metal that reacts readily with oxygen to form three phases of oxide: CuO (tenorite), Cu 2 O (cuprite) and Cu 4 O 3 (paramelaconite) [15]. Among three phases, Cu 4 O 3 phase (paramelaconite is a natural and very scarce mineral) is very rare and difficult to synthesize.…”

“…The recent research articles on Cu 4 O 3 clearly bring out the present state of understanding on their synthesis, optical and electrical properties and their applications [18]. Cu 4 O 3 is a p-type semiconductor with a direct band gap of 2.34 eV and an indirect band gap of 1.50 eV [19]. The binary family of cuprous oxide (Cu 2 O), cupric oxide (CuO) and paramelaconite (Cu 4 O 3 ) has numerous functional applications due to their unique structures and electronic configurations [20].…”

In the present work, Cu 4 O 3 nanoparticles were prepared by biosynthesis method using Razma seeds and copper sulfate as a precursors. The synthesized Cu 4 O 3 nanoparticles were characterized using various analytical tools such as XRD, FTIR, UV-Vis, SEM and TEM. The average crystallite size of the prepared Cu 4 O 3 nanoparticles was calculated by Debye-Scherrer's equation and found to be 13 nm. The TEM images clearly reveal the average size of the particles is 27 nm. Antibacterial activity of Cu 4 O 3 nanoparticles was tested against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria by agar well diffusion method. The cytotoxic activity of synthesized Cu 4 O 3 nanoparticles was examined against human prostate cancer cells (PC-3). The prepared NPs show the significant antioxidant activity through scavenging of 1,1-diphenyl-2-picrylhydrazyl free radicals.

“…There are several reports on the deposition of the Cu 4 O 3 thin films by reactive radio frequency (RF) sputtering by Meyer et al., Murali et al., and Pierson et al . However, it is necessary to obtain enough results on the correlation between the deposition parameters and film properties for better understanding of the optimal process conditions of Cu 4 O 3 thin films.…”

“…However, it is necessary to obtain enough results on the correlation between the deposition parameters and film properties for better understanding of the optimal process conditions of Cu 4 O 3 thin films. Earlier, the mixture ratio of (Ar–O 2 ) sputtering gases have been studied for the deposition of Cu 4 O 3 thin films mostly at room temperature . In our previous study, we have successfully synthesized all the three copper oxides (Cu 2 O, Cu 4 O 3 , CuO) by reactive RF magnetron sputtering by varying the O 2 flow rate as well as adjusting the substrate position .…”

N‐doped Cu4O3 thin films are deposited by radio frequency magnetron sputtering in an ambient of Ar, O2, and N2 using a pure Cu target. The structural, electrical, and optical properties are investigated systematically with the variation of N2 gas flow during deposition. Results reveal that N2 flow rate has a strong influence on both the composition and functional properties of the resulting Cu4O3 films. X‐ray diffraction (XRD) and Raman spectroscopy indicate the formation of the single phase of N‐doped Cu4O3 at a low N2 flow rate of up to 4.3 sccm. From the optical absorption analyses, both undoped and N‐doped Cu4O3 films show a direct forbidden transition at Eg = 1.34–1.44 eV. All the undoped and N‐doped Cu4O3 thin films show p‐type conductivity, and N‐doped Cu4O3 shows lower resistivity on the order of 101–102 Ω cm. These results indicate clearly that N‐doped Cu4O3 is a very promising material for the absorber in low‐cost thin film solar cells.
