It has been demonstrated that copper-induced terbium(III) luminescence sensitization in heterometallic complexes with hydrazine-containing podands is caused by the ligand ring closure and joint coordination of both metal ions to the carbonyl oxygen a

The effect condensed media based on water-soluble polymers (WSPs) have on the luminescence of Eu3+ and Tb3+ complexes with derivatives of benzoic acid and β-diketones is investigated. The effect of WSPs is found to depend on the ratio between the tr

Using the example of europium and terbium complexes with acyl-2-aminobenzoic acids, it is shown that the nonradiative losses of excitation energy in solutions of water-soluble polymers can be decreased both due to the coordination of lanthanide ions

Spectral properties of binuclear zinc complexes in chloroform solutions and polyvinylcarbazole (PVC) films are investigated. It is demonstrated that incorporation of a halogen atom (chlorine or bromine) in a ligand benzene ring leads to a small shift
