Abstract Ternary complexes of rare earth Eu(dbm)3 · phen and Tb(acac)3 · phen (dbm = dibenzoylmethanide, acac = acetylacetone and phen = 1,10-phenanthroline) were introduced into silica gel by the sol-gel method. The result indicated that the rare earth ions (Eu3+ and Tb3+) showed fewer emission lines and slightly lower
emission intensities in the silica gel than in the pure rare earth complexes. The lifetimes of rare earth ions in silica gel (Eu3+ and Tb3+) doped with Eu(dbm)3 · phen and Tb(acac)3 · phen were longer than those in pure Eu(dbm)3 · phen and Tb(acac)3 · phen. A very small amount of rare earth complexes doped in a silica gel matrix can retain excellent luminescence properties.
