abstract |
A series of organic-inorganic hybrid materials composed by lanthanopolyoxotungstates [Ln(W(5)O(18))(2)](n-) (Ln(III)=Eu, Tb, Er and Yb) and 3-hydroxypicolinic acid were prepared using different lanthanide ions. The compounds were characterized by FT-IR and FT-Raman spectroscopy and elemental analysis. The energy transfer processes from the organic ligand to the lanthanide (antenna effect) in these compounds have been studied by photoluminescence measurements. (C) 2007 Elsevier B.V.
