Optical emissions of products sputtered from Fe, Fe2O3 and Fe3O4 powders

Optical Emission From Ion-Bombarded Nickel and Nickel Oxide

“…We observed the same behavior in the case of the massif iron compared with iron powder bombarded by 5 keV Kr + ions. [3] In addition, it is well known that the presence of oxygen modifies the chemical composition of the solid surface and therefore its band structure energy. [13] The structure must be an oxide characterized by its band gap and its electronic affinity.…”

“…The competition between radiative and nonradiative excitation of these particles can be elucidated by optical emission spectroscopy. [2,3] It established that the optical emission of secondary excited particles provides important information on both the formation mechanism of these particles and the possibility of their uses in various applications. [2][3][4][5] These studies show that photon emission is found to be sensitive depending on the surface conditions.…”

“…In our previous work, we described in detail the principle of this method as well as the used equipment. [3,10] This paper was invited for publication in Spectroscopy letters after its presentation, as paper …”

Effects of lithium insertion into vanadium pentoxide thin films. Continuum radiation study

“…Generally, continuum emission observed in front of transition metal targets is believed to arise from excited atom clusters (including diatomic and triatomic) ejected from the solid surface in the sputtering process [11,12]. The continuum radiation observed in the case of transition metals gives rise to a broadband continuum emission which is observed spatially at distances of a few millimeters in front of the target [13,14].…”
