Paper Abstract

The main characteristics of interaction of monokinetic electrons with different energies in the range from 0 to 50 eV at an angle 90 degree(s) (electron energy loss spectra, luminescence excitation functions, and luminescence spectra) for some lasing potential organic materials (paraquaterphenyl, 1,4-bis[2-(5- phenyloxazolyl)]benzene (POPOP), 2,5-biphenyloxazole (PPO), perylene, (beta) -binaphthilenoxide (dinaphthofuran), and 4-methylamino-N-(o-tolyl)-1,8-naphthalimide) are presented and analyzed. It was shown the correlation between elastic and inelastic scattering. It was found that the nature of electron and photon excitations is similar. Direct population of triplet states for most of studied compounds is negligible. The substances with intensive longwave singlet band (perylene, POPOP, PPO, naphthalimide) are very attractive for lasing search in electroluminescent cell. Calculation of excitation rates based on Born approximation results in essential error.
