The complexes Yb(TFN)3(S-BINAPO) (complex 1) and Yb(HFA)3(S-BINAPO) (complex 2) were synthesized, characterized. The absorption as well as PL spectra have been studied. The complex [Yb(TFN)3(S-BINAPO)] showed narrowed emission peak (half width ∼6 nm) at around 981 nm in addition to several emission peaks in NIR (near infrared) region. The complex [Yb(HFA)3(S-BINAPO)] showed strong emission peak at around 985 nm. The charge transfer luminescence of [Yb(TFN)3(S-BINAPO)] was also observed at 412-463 nm.
合成并表征了配合物[Yb(TFN)3(S - BINAPO)]（TFN = 4,4,4 - 三氟 - 1(2 - 萘基)-1,3 - 丁二酮）（配合物1）和[Yb(HFA)3(S - BINAPO)]（HFA = 六氟乙酰丙酮）（配合物2）。研究了其吸收光谱和荧光光谱。配合物[Yb(TFN)3(S - BINAPO)]除了在近红外区域有几个发射峰外，在981 nm左右还显示出变窄的发射峰（半高宽约6 nm）。配合物[Yb(HFA)3(S - BINAPO)]在985 nm左右显示出强发射峰。在412 - 463 nm处也观察到了[Yb(TFN)3(S - BINAPO)]的电荷转移发光。
