ResumoAbstract The terbium ethylenediaminetetra-acetate anion forms a 1:1 mixed ligand complex with the trivalent anion derived from 5-sulphosalicyclic acid. Ultra-violet radiation absorbed by the organic portion of the mixed complex is efficiently converted to the green fluorescence characteristic of Tb 3+ . Quantum efficiency for conversion is greater in D 2 O than in H 2 O solution and is essentially unity in the former solvent at room temperature. The corresponding mixed complex derived from europium ethylenediaminetetra-acetate does not fluoresce.
