[en] Amplitude and time properties of electroluminescence of different rare gases (Ne, Ar, He, N₂) with organic admixtures (alcohols, acetone, acetic acid esters, methylal and toluene) in the proportional chamber are studied. For Ne + isopropyl alcohol mixture (15 mm Hg) there is obtained the largest lightyield exceeding 1.4x10⁴ times the lightyield with scintillation plastic on the basis of polysterene at the same chamber and plastic thickness (1 cm). The best time characteristics are obtained for Ne + acetone mixture (170 mm Hg), for which the total width of half maximum is 20 ns
