摘要
稀土配合物Na3Eu(DPA) 3具有良好的发光特性和热稳定性。采用加热方法将Na3Eu(DPA) 3掺入PMMA树脂中 ,制成发光塑料树脂 ,并测定了其发光性能。结果表明 ,Na3Eu(DPA) 3掺入PMMA树脂后 ,仍保持该稀土配合物原有的发光特性 ,制成的Na3Eu(DPA) 3 PMMA树脂复合材料具有良好的发光性能 ,其发光强度与Na3Eu(DPA) 3掺入的含量有关 。
Based on the intense fluorescence and the highly thermal stability of sodium tris (pyridine dicarboxylato) europate (Na 3Eu(DPA) 3), its composite material with polymethyl methacrylate (PMMA) resin, PMMA: Na 3Eu(DPA) 3, was prepared at 250 ℃. The fluorescence for PMMA: Na 3Eu(DPA) 3 was determined. The results show that the composite material keeps the fluorescence characteristics of the Eu 3+ chelate after PMMA resin is incorporated with the complex Na 3Eu(DPA) 3, and strong orange red emission is observed. The fluorescence intensity for the composite material increases with the increase of the weight ratio of Na 3Eu(DPA) 3 to PMMA resin, non/inearly.
