abstract New lanthanopolyoxotungstoborates, K6-xHx[Ln(BW11O39)(H2O)(3)](.)nH(2)O, Ln(III) = Sm, Eu, Tb, Er, were prepared and characterized by spectroscopic methods (Fourier transform infrared, Fourier transform-Raman, B-11 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(diallyclimethylammonium chloride). The photoluminescence behavior of these final nanostructures was investigated and compared with that of the starting Eu(Ill) polyoxometalate used as the building unit.
