| Electronic absorption spectra of erbium and dysprosium acetate single crystals were measured. The intensities of 4f-4f transitions were calculated and the Judd-Ofelt Ωλ parameters evaluated. Heavy lanthanide acetates differ from other lanthanide carboxylate compounds by relatively high "hypersensitive" transition intensities and the Ω2 parameters. These results are discussed in terms of a stronger polarization effect which can be explained by the distinctly shorter Ln-OH2 bond in comparison with the Ln-OOC bond in the investigated system. |
