“…7b) [37]. The study of the fluorescence spectra of various molecules excited by tunable-energy electrons [37] confirms the previously proposed classification of molecules according to their stability [12,37]. Specifically, highly luminescent aromatic hydrocarbons (polyacenes, polyphe- nyls) are the most stable, while heterocyclic compounds are less stable.…”

“…With increasing electron energy, the fluorescence spectrum can also change due to the addition of the luminescence of decomposition products, depending on the stability of the molecules (Fig. 7b) [37]. The study of the fluorescence spectra of various molecules excited by tunable-energy electrons [37] confirms the previously proposed classification of molecules according to their stability [12,37].…”

We present a brief review of the results of spectroscopic studies of the interaction of a beam of low-energy monokinetic tunable-energy electrons with organic luminescent molecules. Data are presented on elastic scattering, the excitation of vibrational and electronic transitions, luminescence properties, and the formation of positive and negative ions for a number of molecules. It is shown that the passage of electrons through the gaseous and thin-film phases of organic samples is close in nature. For all processes, except the excitation of triplet transitions and the formation of negative ions, the dipole interaction prevails, even in the near-threshold region. The results of the conducted research will be useful for understanding the conversion of electron energy by organic molecules in electronics, where the direct study of elementary processes is very difficult, as well as in biology and plasma chemistry.
