The Au site in Er + Au-implanted silica has been investigated by X-ray absorption spectroscopy, after annealing at 600 Β°C in either neutral N 2 or reducing H 2 (4%):N 2 (95%) atmosphere. High-resolution X-ray fluorescence spectra collected near the Au L III -edge indicate the presence of oxidized Au
