[et al.]. - Текст : непосредственный // Technical Physics. - 2022. - Т. 67, № 15. - P. 2410. - ISSN 1063-7842. - ISSN 1090-6525, DOI 10.21883/tp.2022.15.55268.157-21.
Аннотация: <jats:p> Copper oxide nanoparticles were obtained in the plasma of a low-pressure arc discharge. The effect of the partial pressure of oxygen (10-40%) on the physical properties of the deposited nanoparticles has been studied. X-ray diffraction analysis shows that the cubic structure of Cu<jats:sub>2</jats:sub>O changes to monoclinic CuO with increasing O<jats:sub>2</jats:sub> pressure. The results of Raman spectroscopy further confirmed the phase variations of copper-based oxide nanoparticles. X-ray photoelectron spectroscopy confirmed the change in the binding energy in the oxidation state of nanoparticles. The optical band gap of the deposited Cu<jats:sub>2</jats:sub>O is 2.12 eV, while that of CuO is 1.79-1.82 eV. Keywords: vacuum arc, oxides, nanoparticles, plasma-chemical reactions. </jats:p>
