Abstract

Abstract: The luminescence of Eu(DPA)3 3- induced by beta particles from tritium decay was measured. The solution of Eu 3+ was prepared with europium(III) nitrate hexahydrate and was mixed with a DPA (2, 6-pyridinedicarboxylic acid or dipicolinic acid) solution of pH 11 to yield Eu(DPA)3 3- . The formation of Eu(DPA)3 3- was confirmed through spectrometry. Tritiated water was added to the prepared solution of Eu(DPA)3 3- . The luminescence intensity is proportional to the amount of tritium. In this paper we demonstrate the potential of this Eu complex as an inorganic liquid scintillator.
