用于聚合物光纤的稀土离子配合物光谱特性研究

Spectra characteristic of rare earth-doped polymer optical fiber

采用三种配体苯甲酰丙酮(BA)、苯甲酰三氟丙酮(BFA)、α-噻吩甲酰三氟丙酮(TTFA)与EuCl3和SmCl3合成了六种二元配合物Eu(TTFA)3,Eu(BA)3,Eu(BFA)3,Sm(TTFA)3,Sm(BA)3,Sm(BFA)3,通过测试比较其荧光光谱发现Eu(TTFA)3,Eu(BA)3,Eu(BFA)3在618nm处产生很强的荧光;Sm(TTFA)3,Sm(BA)3,Sm(BFA)3在650nm处有荧光峰产生;通过分析配合物和配体的能级关系,不同配体间发光效率的差异,不同稀土离子的发光特性的差异,发现了TTFA是Sm3+和Eu3+的优良配体,Eu3+具有较高的发光效率。在Sm3+和Eu3+的共掺杂中,选取TTFA做配体,发现Sm3+对Eu3+有明显的敏化效应。

Six complexes of Eu(TTFA)3,Eu(BA)3,Eu(BFA)3,Sm(TTFA)3,Sm(BA)3,Sm(BFA)3 were compounded by using three ligands,which are Benzoylacetone(BA) α-thenoyltrifluoroacetone(TTFA) 3-benzoyl-1,1,1-trifluoroacetone(BFA).The fluorescence Properties of above six complexes were measured.The results showed that the complex of Eu(TTFA)3,Eu(BA)3,and Eu(BFA)3 existed a strong fluorescence in 618nm,and Sm(TTFA)3,Sm(BA)3 and Sm(BFA)3 existed a fluorescence peak in 650nm.The relationship of energy level between complex and liga...
