Lanthanopolyoxotungstoborates: synthesis, characterization, and layer-by-layer assembly of europium photoluminescent nanostructured films

J Nanosci Nanotechnol. 2004 Jan-Feb;4(1-2):214-20. doi: 10.1166/jnn.2004.073.

Abstract

New lanthanopolyoxotungstoborates, K6-xHx[Ln(BW11O39)(H2O)3].nH2O, Ln(III) = Sm, Eu, Tb, Er, were prepared and characterized by spectroscopic methods (Fourier transform infrared, Fourier transform-Raman, 11B solid-state nuclear magnetic resonance, and photoluminescence) and elemental analysis. A layer-by-layer assembly method was employed to fabricate multilayered films containing the europium heteropolyanion and the polyelectrolytes poly(sodium 4-styrenesulfonate) and poly(diallydimethylammonium chloride). The photoluminescence behavior of these final nanostructures was investigated and compared with that of the starting Eu(III) polyoxometalate used as the building unit.
