  Upconverted Photosensitization of Tb Visible Emission by NIR Yb Excitation in Discrete Supramolecular Heteropolynuclear Complexes

  摘要：

  Addition of Tb3+ salts to a solution of a (YbLD) complex in D2O resulted in the formation of [(YbLD)(2)Tb-x] (x = 1 to 3) complexes that, upon NIR excitation at 980 nm, showed an unprecedented Yb to Tb upconversion sensitization phenomenon resulting in the observation of the typical green emission of Tb.

• Quantification of C−H Quenching in Near-IR Luminescent Ytterbium and Neodymium Cryptates

  DOI：10.1021/ja105768w

  日期：2010.10.20

  Two series of selectively deuterated cryptates with the lanthanoids Yb and Nd have been synthesized, and the luminescence lifetimes for the corresponding near-IR emission bands have been measured. Global fitting of these lifetime data combined with structural analysis allows for the accurate quantification of the contributions of individual C-H oscillators groups in the ligand to the nonradiative deactivation rates of the emissive lanthanoid states.
• Anomalous Reversal of C–H and C–D Quenching Efficiencies in Luminescent Praseodymium Cryptates

  DOI：10.1021/ja306052u

  日期：2012.8.29

  A series of selectively deuterated praseodymium cryptates has been synthesized. Their luminescence lifetimes in solution range from 150 to 595 ns for the (1)D(2) → (3)F(4) transition. Global fitting of the nonradiative deactivation rate differences of the isotopologic C-(H/D) oscillators revealed that aromatic C-D overtones anomalously quench the luminescence more than C-H vibrations. This is explained by the dominance of Franck-Condon overlap factors that greatly favor C-D oscillators, which are in almost ideal resonance with the relevant energy gap (1)D(2)-(1)G(4) of praseodymium.
