Polymer LB films containing europium complexes (p(DDA/Eu(TTA)3Phen)) were prepared by spreading a mixed solution of pDDA (= poly(N-dodecylacrylamide)) and Eu(TTA)3Phen (= 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanediono)-1,10-phenanthroline europium(III)) onto a water subphase in which the complexes and their ligand groups were saturated. From the surface pressure - area isotherms, it was found that p(DDA/Eu(TTA)3Phen) takes a condensed monolayer formation. The monolayer could be transferred on solid substrates as Y-type LB films. The spectroscopic properties of Eu(TTA)3Phen in the polymer LB films were investigated by fluorescence spectroscopy and time-resolved luminescence decay measurement.
