Phosphorescent bimolecular and termolecular exciplexes of 3Ru(bpy)32+ and Ru(phen)32+ (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.
