Abstract: A homogeneous distribution of luminescent lanthanide(III) 2-thenoyltrifluoroacetonate complexes
(Ln ) Pr, Nd, Sm, Eu, Dy, Ho, Er, Tm, Yb) in an organic-inorganic hybrid material was obtained by
grafting the complexes to the solid matrix via 2-substituted imidazo[4,5-f]-1,10-phenanthroline moieties.
Thin films of the silica hybrid material were prepared by the sol-gel method and by spin-coating of the
gelating solution on glass slides or on oxidized silicon wafers. The thickness of the thin films was
determined by scanning electron microscopy (SEM). High-resolution luminescence spectra of the lanthanide
complexes were recorded, and the luminescence decay times were measured. The luminescence quantum
yields of europium(III)-doped thin films exposed to different drying conditions were determined by using
an integrating sphere.
