Abstract
A binary and ternary rare earth complexes were synthesized. The structure and composition of the complexes were characterized by FT-IR and Elemental Analyzer. It is found that the complexes have excellent fluorescence intensity and thermal stability. Photoluminescent measurements show that Phenanthroline (Phen) could efficiently transfer energy to Eu3+ and sensitize the luminescence of Eu3+. The copolymers of complexes, methyl methacrylate (MMA) and methacrylic acid (HMA) emit characteristic fluorescence of Eu3+. The fluorescence intensity enhanced with the complexes content increasing. But the apparent copolymers of Eu(AA)3 have stronger luminous intensity than that of Eu(AA)3Phen under limit solubility because Phen reduces the content of solvable Eu3+ in the mixture of MMA and HMA.
