A comparison of the emission spectra of excited yttrium atoms ejected from the surface of the metal yttrium and yttrium-aluminum garnet (YAG) by Ar+ ions with energy 20 keV to the emission spectra of excited yttrium atoms ejected from the surface of metal yttrium by Xe+ ions with energy 40 keV has been made. A sharp increase of population states of yttrium atoms with low energy excitation (z 2D°,...
The main parameters of ion-photon emission (IPE) during bombardment of yttrium aluminum garnet (YAG – Y 3 Al 5 O 12 ) with Ar + ions were determined. An essential difference was found in the spectral composition of the emission from YAG in comparison with that of constituent metals (Al and Y). It was supposed that the difference in the spectra of IPE is due to the different...
Investigations of the main parameters of ion–photon emission during Ar + ion bombardment of Fe and Co metals and Fe–Co alloys have been made. It was shown that the dependence of the quantum yields of the emissions of ejected excited Fe and Co atoms on the concentration of corresponding elements in the alloys generally decreased but showed local maxima. These maxima are related to concentrations...
