“…On the whole, we have measured the EELSs and radiative properties for many molecules in the gas phase: polyphenyls and polyacenes [20], oxazoles and oxadiazoles [21], perylene [22], naphthalimide [23], fluorene-like molecules [17, 24±26], organic complexes of europium [27], dibenzoxazolylbiphenyl [28], DPEA [15], Alq 3 and triphenyldiamine [18], Irppy 3 [16], cyanines [29], etc.…”

“…The FEF magnitude is the result of the excitation of all electronic states for a given electron energy with the inclusion of the fluorescence quantum yield, i.e., the behavior of the FEF largely reflects the intramolecular energy exchange as well as the efficiency of the electron-molecular interaction. Then, the fluorescence EF W f l E can be defined as [3,22] W f l E jaen 0 hn sE exc gE exc dE exc , where j is the current density, e is the electron charge, n 0 is the density of molecules, hn is the fluorescence photon, and gE exc is the dependence of the fluorescence quantum yield on the electron energy.…”

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.
