Based on the strong fluorescence and the highly thermal stability of sodium tris (pyridine dicarboxylato) europate (Na3Eu(DPA)3), polymethyl methacrylate (P MMA) composite material incorporated with the complex, PMMA: Na3Eu(DPA)3, w as prepared at 250 ℃. The fluorescence behavior of PMMA: Na3Eu(DPA)3 mater ial was examined. The results show that the composite material keeps the lumin escent characteristics of the Eu3+ chelate after PMMA is incorporated wit h Na3Eu(DPA)3, and strong orange-red emission of the composite was observed . The fluorescence intensity of the composite material increases with the increa se of the weight ratio of Na3Eu(DPA)3 to PMMA, but the relationship is not linear.
