The fabrication and photophysical characterization of polymeric fiber preforms, obtained from a polymerization process of poly(methyl methacrylate) (PMMA) doped with terbium(III)-tris-(2,2,6,6-tetramethyl-3,5-heptanedionate) (Tb(tmhd)3) at 1.12–1.13 mmol concentration and co-doped with europium(III)-tris-(2,2,6,6-tetramethyl-3,5-heptanedionate) (Eu(tmhd)3) at different concentrations, is reported. The preforms show a variation in photoluminescent emission due to energy transfer from Tb3+ to Eu3+ embedded in PMMA matrix. FTIR and FTR spectroscopy measurements indicate that lanthanide complexes are not chemically bonded to the polymeric matrix, however, the successful interaction between them, enables the formation of a composite with excellent multicolor photoluminescent properties. Moreover, thermal resistance of PMMA doped with the Ln(tmhd)3 complexes improves (∼100 °C). The best thermal properties were obtained for a 1.12 and 2.62 mmol concentration of Tb3 and Eu3+ complex in PMMA respectively.
