聚甲基丙烯酸甲酯对Eu(DBM)_3Phen配合物荧光性质的影响

Study on the effect of PMMA on the fluorescence properties of Eu(DBM)_3Phen complex

通过将合成的稀土络合物Eu(DBM)3Phen掺杂到等离子法合成的聚甲基丙烯酸甲酯(PMMA)中,制备出含不同分子量PMMA的Eu(DBM)3Phen/PMMA复合膜,并研究了PMMA聚合度对复合膜荧光性能的影响.结果表明,Eu(DBM)3Phen能够很好地分散在PMMA聚合膜中,这种复合膜显示出很强的橙红色荧光,并且复合膜的荧光强度随着聚合物分子量的增加而增强.

Eu（DBM）3Phen/PMMA composite films with different molecular weight PMMA are successfully synthesized by incorporating the complex Eu （DBM）3Phen into PMMA made by plasma synthesis. The effect of PMMA on the fluorescence properties of Eu（DBM）3 Phen complex is investigated. The results indicate that Eu （DBM）3Phen complex is homogeneously dispersed in PMMA films, which leads to a remarkable increase of the fluorescence properties of the polymeric films. The fluorescence intensity of the luminescent membrane increase with the molecular weight of PMMA polymer increasing.
