Abstract

This paper discusses the sensitized fluorescence of coumarin-30 in nanoparticles self-organized from complexes of phenylbenzoyltrifluoroacetone and 1, 10-phenanthroline with ions of the lanthanides, yttrium, aluminum, and scandium in water–alcohol solutions. It is shown that, when nanoparticles are formed from complexes of lanthanide and yttrium ions, the coumarin-30 molecules from the solution are completely incorporated into the nanoparticles. An absence of concentration quenching of the cofluorescence of coumarin-30 in the nanoparticles is detected in the entire region of dye concentrations studied here. Facts are presented that prove that coumarin-30 is incorporated in the lanthanide and yttrium complexes as a synergic bidentate ligand. It is demonstrated that brightly luminescent markers can be created that absorb not only in the 360–370 nm region, but also in the 440–450 nm region and that possess a narrow fluorescence spectrum with a maximum at λ=520 nm.
