Luminescence from [Ru(bipy)3]2+ ions adsorbed on ion exchange surfaces. Dynamic quenching reactions between adsorbed cations
Abstract
Luminescence lifetime measurements show that when both luminescent and quencher ions are adsorbed on cation exchange resin luminescence quenching takes place by dynamic bimolecular processes involving energy transfer or electron transfer at rates which are of the same order as those in homogeneous solution.
