The chemical state and coordination state of copper ions have been studied in 2 MeV, 1 × 1017 Cu+ ions/cm2-implanted silica glass by X-ray absorption fine structure spectroscopy. It was found that the implanted Cu atoms are mainly present as Cu(I) state in the glass from the comparison of X-ray absorption near edge structure spectrum of the glass with those of CuO, Cu2O, CuAlO2, CuFeO2, Ca2CuO3 and MgCu2O3 crystals. We inferred from the extended X-ray absorption fine structure spectra that the implanted Cu atoms are coordinated by two oxygen atoms and the Cu-O interatomic distance is 0.188 nm in the glass.
