Effect of Bombardment with Oxygen Ions on the Surface Composition of Polycrystalline Silver

Аннотация

Surface layers of polycrystalline silver bombarded with oxygen ions having energies from 100 to 300 eV are studied via Auger electron and X-ray photoelectron spectroscopies. Atomic and molecular oxygen together with silver in the zero-valence state are found in AgO and Ag₂O after such treatment in silver surface layers. In addition, there is positive displacement of the Ag 3d_3/2 peak by 0.5 eV, indicating an increase in spin-orbit splitting for Ag 3d_5/2–Ag 3d_3/2.
