Investigation of organic systems by ion-photon spectroscopy

We study spectral composition, quantum yield and spatial intensity distribution of radiation of excited particles, escaping from the surface of some organic dyes and their mixtures with lipids under bombardment by Ar+ ions. Essential influence of the method of target preparation from organic compounds on the yield of the excited particles is demonstrated. The processes resulting in formation of excited particles under ion bombardment of complex organic systems are specified. The model of interaction of lipids with organic dyes is proposed.
