In this paper, formation of binary and ternary lanthanide coordination polymers of 2-hydroxynicotinic acid and 1, 10-phenanthroline was achieved through the polymerization process of MMA monomer. Then the transparent hybrid thick films were in-situ composed with lanthanide (Ln = Dy, Tb, Eu) coordination polymers ([Ln(HnicO)(3)](n), [Ln(HnicO)(3 center dot)phen](n)) and polymethyl methacrylate (PMMA). The luminescence properties and energy transfer for these polymeric composite films were studied with absorption spectra, IR spectra, fluorescent emission spectra in detail. All the hybrid thick films composed with dysprosium, terbium and europium coordination polymers show respective characteristic emission of the lanthanide ions. Besides, terbium and the europium complex co-doped thick films also have been achieved. In the terbium and the europium complex co-doped thick films, luminescent intensity of Eu3+ have been improved with the adding of the terbium complex.
