Abstract: By using (3-trimethoxysilylpropyl) ethylenediamine (TSPED) and a dental material (acrylic resin) as precursors, self-standing films doped with the luminescent complexes Eu(fod)(3).2H(2)O and Eu(fod)(3).terpy were prepared. The doped films were so studied from a spectroscopic point of view. Is verified that the film composition exerts remarkable effects on both, the intensity and lifetime of the emission process. Acrylic resin films reduces the intensity of the emission process, but increases the lifetime,of a such process, in comparison with TSPED films, for which an opposite behavior is observed. The measured lifetimes for the emission process for the compounds Eu(fod)(3).2H(2)O in TSPED and acrylic resin films are 306 and 369 mus, respectively. For the same film matrices, the measured lifetimes for the complex Eu(fod)(3).terpy gave the values 347 and 880 mus, respectively. (C) 2002 Editions scientifiques et medicales Elsevier SAS.
