Popis: Spectral-luminescence characteristics of Ln 3+ ions, emitting in the near-infrared (IR) spectral region, in solutions of their complexes with some organic ligands (dyes) have been considered. Complexes can be excited with visible light ( λ exc =532 nm ). 4f-Luminescence as a result of energy transfer from the dye moiety to the lanthanide ion has been shown. The luminescence is higher with complexes of macrocyclic polydentate ligands as compared with their acyclic analogues due to less content of water molecules in the coordination center.
