Er_xYb_(1-x)(TPB)_3Bath(x=0,0.218,0.799,0.896,0.987,1)配合物的近红外发光性能（英文）

Near Infrared Luminescence Properties of the Complexes of Er_xYb_(1-x)(TPB)_3Bath(x=0,0.218,0.799,0.896,0.987,1)

采用4,4,4-三氟-1-苯基-1,3-丁二酮(TPB)为第一配体,4,7-二苯基-1,10-菲咯啉(Bath)为第二配体,分别制备了配合物Er(TPB)3Bath和Yb(TPB)3Bath,以及它们的混合配合物ErxYb1-x(TPB)3Bath(x=0.218,0.799,0.896,0.987),并对所制得配合物的发光性能进行了系统研究。研究结果表明,所有配合物均能发射所含稀土离子的近红外特征光,并且可以通过调节混合配合物中的nEr/nYb来调控Yb^(3+)/Er^(3+)之间的能量传递,进而提高Er^(3+)离子在1 530 nm处的发光。

A series of near infrared（NIR） luminescent complexes based on ErxYb1-x（TPB）3 Bath（where TPB=4,4,4-tri-fluoro-1-phenyl-1,3-butanedione, Bath =4,7-diphenyl-1,10-phenanthroline, x =0, 0.218, 0.799, 0.896, 0.987, 1,respectively） were prepared by selecting TPB and Bath as the first and second ligands, respectively. Luminescence properties of these complexes were investigated in detail. All these complexes exhibit the characteristic emission of the Yb3＋ and/or Er3＋ ion in the NIR region, and the emission intensity of Er3＋ion can be enhanced by modulating the nEr/nYb, which is related to the energy transfer from Yb3＋ to Er3＋ ions.
