Ait El Fqih, A. El Boujlaïdi, R. Jourdani, A. Kaddouri] The spectral structure of the radiation (250-500nm) emitted during sputtering of clean and oxygen-covered polycrystalline vanadium and V2O5 by 5keV Kr+ ions is presented. The optical spectra obtained by bombarding the vanadium target consist of series of sharp lines, which are attributed to neutral and ionic excited V. The same lines are observed in the spectra of V2O5 and vanadium when oxygen is present. The absolute intensities of VI and VIIlines are measured under similar conditions for all spectra. The difference in photon yield from the clean and oxide vanadium targets is discussed in terms of the electron-transfer processes between the excited sputtered and electronic levels of the two types of surfaces. We have examined the existing models of ionisation, excitation, neutralisation and de-excitation of atomic particles in the vicinity of solid surfaces. Continuum radiation was also observed and interpreted as a result of the emission of excited molecules of the metal-oxide. EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2011 Ait El Fqih M.
