Abstract

X-ray photoelectron spectra of evaporated V2O5 and co-evaporated V2O5/B2O3 thin films have been investigated. The photoelectron spectrum of a simple V2O5 film shows the splitting of the V 2p level in accordance with the spins. The values of binding energies corresponding to V 2p and O1s are comparable with those reported previously. For co-evaporated V2O5/B2O3 films a chemical shift in the O 1s level has been observed which has been attributed to the changed chemical environment of oxygen as a result of the presence of boron and vanadium atoms. The values of binding energies for V 2p3/2 and O 1s corresponding to simple evaporated V2O5 and co-evaporated V2O5/B2O3 show the presence of V2O4 species in the films.
