Coordination Field Analysis of the Polarized Luminescence Spectra of Tb3+ in Trigonal Na3[Tb(C4H4O5)3]·2NaClO4·6H2O

Abstract

Abstract: The coordination field perturbation energies of Tb³⁺ in single crystals of trigonal dihedral(D₃) symmetry Na₃[Tb(C₄H₄O₅)₃]·2NaClO₄·6H₂Oare calculated and the polar-ized luminescence spectra in the 7FJ→5D₄(J=1～6) transition regions are assigned theoreti-cally. The results of the double-sphere coordination point-charge field (DSCPCF) model are in reasonably good agreement with the experimental observation and are superior to that of the simple static coordination point charge field(PCF) model.

Key words: Coordination field calculation, Spectral analysis, Rare earth complex, TbODA
