Abstract

AbstractThe surface modification of oxides MoO3and WO3 under irradiation by Ar+ ions with an energy of 3 keV in high vacuum is investigated by X‐ray photoelectron spectroscopy. It is shown that under irradiation by Ar+ ions lower and intermediate oxides and unoxidized metals are formed in the surface layers of higher oxides. It is found that the process of ion‐beam reduction of the surface of oxides MoO3and WO3 substantially depends on the irradiation dose and difference in energy of the metal–oxygen bond in oxides.
