Clean and oxygen-covered nickel and nickel oxide were bombarded by 5 keV krypton I ions under a relatively high vacuum. Optical spectra resulting from ion bombardment of the nickel target consist of series of sharp lines attributed to the neutral nickel. These lines were observed in the spectra of clean nickel and nickel oxide at the same wavelengths but with different intensities. The difference in the observed photon yield is discussed in terms of the electron transfer processes between the excited sputtered and electronic levels of the surface.

“…For a large number of incident ions (about 2 × 10 5 Kr + atoms), the ratios of Fe, Cr, and Al atoms emitted in the solid angle corresponding to each probe were counted. The SRIM software requires the introduction of several parameters; the cinematic conditions considered are that usually used in various experiments [16,17]. The three remaining parameters are phenomenological ones, i.e.…”

Iron, chromium and aluminum particles sputtered under 5 keV by Kr + ion bombardment at normal incidence from the ternary alloy Fe82Cr6Al12 was simulated. The Stopping and Range of Ions in Matter (SRIM) software combined to a new code-program, called Angulaire, were used to obtain the sputtering yields and angular distributions of the ejected species. The simulation was performed for a large number of incident ions (about 2 × 10 5 ions) and the number of particles emitted in the solid angle corresponding to the probe was counted by a computer. The angular distributions of sputtered particles were compared with the results available in the literature and showed a reasonable agreement. Furthermore, we have demonstrated that the angular distribution of the differential sputtering yields of all ejected species (iron, aluminum, and chromium) from the ternary alloy exhibited an over-cosine tendency.

The lithiated/delithiated vanadium pentoxide films deposited by sol-gel spin coating on indium tin oxide-coated glass substrates were analyzed by sputter-induced photon spectroscopy, X-ray diffraction, and optical absorption techniques. First, it is shown that the crystalline structure of where Li + ion is the host material and x the molar intercalation fraction.During the intercalation reaction, the vanadium atoms are considered to be partially reduced from V 5+ to V 4+ formal oxidation state, when 0 ≤ x ≤ 1. 6 The insertion/deinsertion processes of Li ions into V 2 O 5 matrix are often accompanied by electronic structure changes. V 2 O 5 as base material is semiconductor characterized by an energy gap and Na x V 2 O 5 10 deposited by physical vapor deposition technique.Note that these results were obtained by photoelectron spectroscopy (XPS and UPS). Concerning the deposition methods, they were listed by Granquist. 11 Besides, the properties of V 2 O 5 films show strong dependence on the synthesis procedures. Furthermore, the intercalation of lithium ions into V 2 O 5 leads to several changes in the electronic structure and optical and electrical properties. Hence, various electroanalytical techniques [12][13][14] have been used to explain the mechanisms of Li intercalation into this oxide.Using X-ray diffraction (XRD), optical absorption spectroscopy, and sputter-induced photon spectroscopy (SIPS) techniques, we investigate in this study the effect of Li insertion and deinsertion on the host lattice of V 2 O 5 thin film prepared by sol-gel spin coating procedure.The structure and optical absorption properties of clean, intercalated, and deintercalated V 2 O 5 films are discussed. The luminescence spectra resulting from 5 keV Kr + ion bombardment are also reported. The observed lines are all identified, and their intensities before and after
