title: [Characterization of Ru(bpy)(3)2+ and Ru(phen)(3)2+ complexes with silver(i) ion of ground state in propylene-carbonate].
abstract: Phosphorescent bimolecular and termolecular exciplexes of 3Ru(bpy)(3)2+ and Ru(phen)(3)2+ (bpy = 2,2'-bipyridine, and phen = 1,10-phenathroline) formed by silver ions of ground state in propylene carbonate solution are identified and characterized. Formation constants, lifetime, radiative and non-radiative decay constats of exciplexes are determined. Temperature-dependent luminescence lifetime measurements have revealed that exciplex formation causes a decrease in the energy level of the luminescent excited state.
