Interaction of lanthanide β-diketonate complexes with polyvinylpyrrolidone: proton-controlled switching of Tb3+ luminescence.


In the present study the interaction of lanthanide β-diketonate complexes with polyvinylpyrrolidone (PVP) has been systematically investigated using fluorescence spectroscopy. The emission of terbium complexes with hexafluoroacetylacetone (hfa) ligands is almost completely quenched by PVP in the absence of H(+) ions, while it is enhanced by more than 30… (More)
