  A luminescent quadruple stranded dinuclear Eu(III) complex based on 2,8-bis(4′,4′,4′-trifluoro-1′,3′-dioxobutyl)-dibenzothiophene for light-emitting diodes

  摘要：

  A luminescent quadruple stranded dinuclear Eu(III) complex Na-2[Eu-2(dbt)(4)] was synthesized, where H(2)dbt was 2,8-bis(4',4',4'-trifluoro-1',3'-dioxobutyl)-dibenzothiophene. The complex emits the characteristic red luminescence of Eu3+ ion due to the D-5(0) -> F-7(J) (J = 0-4) transitions under 395 rum-light excitation with a luminescent quantum efficiency of 23%. Bright red light-emitting diodes (LEDs) were fabricated by coating the complex onto 395 nm-emitting InGaN chip. The results indicate that the complex may act as a red component in the fabrication of near UV-based white light-emitting diodes with high color-rendering index. (C) 2009 Elsevier B.V.
