![عکس صفحه اول مقاله: NIR and CT luminescence spectra of [Yb(TFN)(S-BINAPO)] and [Yb(HFA)(S-BINAPO)] complexes NIR and CT luminescence spectra of [Yb(TFN)(S-BINAPO)] and [Yb(HFA)(S-BINAPO)] complexes](/preview/png/1230322.png)
• The complexes [Yb(TFN)3(S-BINAPO)] and [Yb(HFA)3(S-BINAPO)] showed PL at low temperature.
• Complex [Yb(TFN)3(S-BINAPO)] showed narrowed emission (half width ∼6 nm) at 981 nm.
• The complex [Yb(HFA)3(S-BINAPO)] showed strong emission peak at around 985 nm.
• Complex [Yb(TFN)3(S-BINAPO)] showed CT emission at 412–463 nm.
The complexes [Yb(TFN)3(S-BINAPO)](TFN = 4,4,4-trifluoro-1(2-napthyl)-1,3-butanedione) (complex 1) and [Yb(HFA)3(S-BINAPO)](HFA = hexafluoroacetylacetonate) (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.
