Abstract

This study is devoted to luminescent properties of the new [Yb(L)3(phen)] complex with near-infrared emission, where L is the anion of 4,4,4-trifluoro-1-(naphthyl-2)butane-1,3-dione, and phen is 1,10-phenanthroline. It is shown that the electronic excitation energy can be efficiently transferred to Yb³⁺ ion electronic levels by selecting the ligand environment. To study the electroluminescent properties, a multilayer organic light-emitting diode (OLED) with the ITO/PEDOT:PSS/PVK/Yb-complex/TPBi/LiF/Al structure is designed. The efficiency of the fabricated infrared OLED is close to the record values presented in the literature for the close type of the Yb³⁺ complexes.

含有吡唑取代的 1,3-二酮和 1,10-菲咯啉的 Yb3+ 配合物的光和电致发光特性

摘要

本研究致力于研究具有近红外发射的新型 [Yb(L)3(phen)] 配合物的发光特性，其中 L 是 4,4,4-trifluoro-1-(naphthyl-2)butane- 1,3-二酮，phen 是 1,10-菲咯啉。结果表明，通过选择配体环境，可以将电子激发能有效地转移到 Yb ³⁺离子电子能级。为了研究电致发光特性，设计了具有 ITO/PEDOT:PSS/PVK/Yb-complex/TPBi/LiF/Al 结构的多层有机发光二极管 (OLED)。制造的红外 OLED 的效率接近文献中给出的 Yb ³⁺配合物的密型的记录值。
