Preparation of Photoluminescent Compounds of Eu(III), Sm(III), and Dy(III) Containing Anions of Tetrafluoroterephthalic Acid

摘要

The Ln2(H2O)4(L)3·2H2O and Ln2(phen)2(L)3·2H2O complexes [Ln = Eu(III), Sm(III), or Dy(III); H2L = C6F4(COOH)2, phen = 1,10-phenanthroline] have been prepared. Structures of the prepared compounds have been confirmed by X-ray diffraction and IR spectroscopy studies. The complexes of Eu(III) have exhibited red photoluminescence stronger than that of the complexes of Sm(III) and Dy(III).
