Experimental research of the sensitization effect of Eu3+, Sm3+, Tb3+ and TTFA polymers

摘要: 为了研究稀土离子的α-噻吩甲酰三氟丙酮(α-thienyltrifluoroacetone,TTFA)配合物中敏化发光效应,对自行制备出的稀土离子Eu3+,Sm3+和Tb3+单掺TTFA配合物Eu(TTFA)3,Tb(TTFA)3,Sm(TTFA)3及3种稀土离子两两共掺的配合物的荧光光谱进行了分析,得出了稀土离子Eu3+,Sm3+,Tb3+与配体TTFA的敏化特性以及稀土离子Eu3+,Sm3+和Tb3+之间的敏化特性。Eu(TTFA)3,Tb(TTFA)3,Sm(TTFA)3及3种稀土离子共掺的配合物中,稀土离子Eu3+,Sm3+,Tb3+与配体TTFA及Eu3+,Sm3+,Tb3+之间有明显的敏化效应。结果表明,将其用于聚合物光纤放大器具有良好的发展前景。

Abstract: In order to study the sensitization effect of Eu3+,Sm3+,Tb3+ and α-thienyltrifluoroacetone(TTFA) polymers,rare earth complex-doped polymers and rare earth ions complex-co doped polymers was made from the rare earth ions Eu3+,Sm3+,Tb3+ and TTFA.The fluorescence properties of these chelate complexes in ethanol were investigated.Sensitization effect properties of rare earth complex-doped polymers and rare earth ions complex-co doped polymers were found.The study results can be used in polymer optical fiber amplifiers with good development.
