Ternary complexes of terbium with ortho (and para) aminobenzoic acid and 1.10 phenanthroline were introduced into silica gel by the sol-gel method. The luminescence behavior of the solid-state samples was studied during the sol-gel aging process by means of emission, excitation spectra, lifetimes and quantum efficiencies.
