【摘要】 用新的合成方法合成了稀土配合物Eu(TTA) 3Phen。研究了该配合物的IR、UV、TGA、元素分析和荧光光谱。该配合物具有良好的发光性能和热稳定性。采用加热方法将Eu(TTA) 3Phen掺入PMMA树脂中 ,制成发光塑料树脂 ,并测定其发光性能。结果表明 ,Eu(TTA) 3Phen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Eu(TTA) 3Phen -PMMA树脂复合材料具有良好的发光性能 ,其发光强度与Eu(TTA) 3Phen掺入的含量有关。更多还原

【Abstract】 Rear earth complex Eu(TTA) 3Phen was synthesized with a new method,the product were characterized by element analysis,IR,UV,TGA and fluorescence spectra.The strong fluorescence and high thermal stability of Eu(TTA) 3Phen were used for modification of resin.The exitation emission spectra showed that the prepared Eu(TTA) 3Phen-PMMA composite material retained the fiuorescence characteristics and strong red emission of Eu 3+ complex and its fluorescence intensity was found to be increased with increase in the mass fraction of Eu(TTA) 3Phen in PMMA resin.更多还原
