摘要

A luminescent quadruple stranded dinuclear Eu(III) complex Na2[Eu2(dbt)4] was synthesized, where H2dbt was 2,8-bis(4',4',4'-trifluoro-T,3'-dioxobutyl)-dibenzothiophene. The complex emits the characteristic red luminescence of Eu~(3+) ion due to the ~5D_0 -> ~7F_J (J = 0-4) transitions under 395 nm-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.
