It is established that a fairly intense luminescence of thulium can be observed in solutions (suspensions of residues) of different-ligand complexes that include β-diketone and an organic base. The luminescence characteristics of Tm compounds are de

Luminescence quenching of lanthanides in complexes with β-diketones containing different fluorinated radicals

Autor: Svetlana B. Meshkova, M. O. Lozinskii, Z. M. Topilova, D. V. Bol'shoi

Publikováno v: Journal of Applied Spectroscopy. 64:229-233

It is shown that luminescence quenching of lanthanide (Ln) ions by water molecules (OH-oscillators) entering the first coordination sphere of a complex decreases as the chain of the fluorinated radical lengthens from CF3 to C6F13. The amounts of wate

Publikováno v: Scopus-Elsevier

Quantum yields and lifetimes of 2 F 5/2→2 F 7/2 fluorescence are measured for double and heteroligand complexes of ytterbium with dibenzoylmethane and thenoyltrifluoroacetone, as well as their analogs with a deuterated central C-H group dissolved i
