The electronic structure of single atoms of Ag and Au implanted in SiO2 has been examined using X-ray photoemission. In this dilute limit the valence band narrows by 1- eV, approaching the expected shape of the gas phase free atom. This observation supports a model for the implanted atom where the influence of the SiO2 matrix only slightly perturbs the atomic wavefunctions of the free atom.
