Infrared and X-Ray Absorption Spectra of Cu₂O and CuO Nanoceramics

Abstract:

We present the results of the study of middle infrared absorption (MIR) and X-ray absorption (XAS) spectra of nanostructured CuO and Cu₂O ceramics prepared by the high pressure torsion method from coarse-grain oxide powders. We have found that the MIR bands at ~140 meV in CuO and Cu₂O nanoceramics are associated with the presence of Cu⁺ and Cu²⁺ ions, respectively. X-ray absorption spectra indicate an appearance of extra Cu²⁺ and Cu⁺ ions in nanoCu₂O and nanoCuO ceramics, respectively.
