A High Resolution Luminescence Study of two Novel Salts of the Triethvlenetetraaminehexaacetatoeuropate(III) Anion

A low-temperature high-resolution luminescence study of K 3 Eu(TTHA)·H 2 O and T1 3 Eu(TTHA) ·H 2 O has been carried out. the Eu 3+ luminescence spectrum was recorded over the spectral range which includes transitions from the 5 D 0 excited state to the 7 F 0-4 ground state manifolds. the observed s...

Description
Summary:A low-temperature high-resolution luminescence study of K 3 Eu(TTHA)·H 2 O and T1 3 Eu(TTHA) ·H 2 O has been carried out. the Eu 3+ luminescence spectrum was recorded over the spectral range which includes transitions from the 5 D 0 excited state to the 7 F 0-4 ground state manifolds. the observed spectral patterns are analyzed using group theoretical methods so as to deduce the site symmetry of the Eu 3+ ion in the complex. the analysis shows that the Eu 3+ ion occupies a spectroscopic site symmetry that approaches a D 2 symmetry with distortion towards a C 2 or lower symmetry in the potassium salt and a site symmetry of a C 3 in the thallium salt. These salts illustrate the potential of the counterion to markedly influence the effective site symmetry of the Eu 3+ ion.
