| Abstract: | The main parameters of the ion-photon emission (IPE) arising from the bombardment of yttrium-iron garnets (YIG) samples with Ar+-ions were studied. The essential difference in the spectral composition, quantum yield of emissions, and spatial distribution of radiation registered from YIG to that from samples of pure metal iron was determined. Such difference in parameters of IPE is due to contribution of new mechanisms of formation of excited particles leaving the sample during ion bombardment YIG compared with emission from a metal. It was suggested the excited atoms are formed during the decay of MemOn complexes ejected from solids. |
