Gusev AN, Shul'gin VF, Nishimenko G, Hasegawa M, Linert W - Synth Met (2013)

Bottom Line: Luminescent properties of two heteroleptic dibenzoylmethanate europium(III) complexes with 1,3-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)propane (H2L(1)) and 1,4-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)butane (H2L(2)) as ancillary ligands are described.The two double-layer-type electroluminescent cells with the structures: (1) ITO/NPB(40 nm)/Eu(DBM)2HL(1) (40 nm)/LiF (1 nm)/Al (100 nm) and (2) ITO/NPB(40 nm)/Eu(DBM)2HL(2) (40 nm)/LiF (1 nm)/Al (100 nm) emit red light originating from the europium complexes.The device 2 gives the maximum brightness of 455 cd/m(2) at 19.2 V.

ABSTRACT
Luminescent properties of two heteroleptic dibenzoylmethanate europium(III) complexes with 1,3-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)propane (H2L(1)) and 1,4-bis(5-pyridin-2-yl-1,2,4-triazol-3-yl)butane (H2L(2)) as ancillary ligands are described. The two double-layer-type electroluminescent cells with the structures: (1) ITO/NPB(40 nm)/Eu(DBM)2HL(1) (40 nm)/LiF (1 nm)/Al (100 nm) and (2) ITO/NPB(40 nm)/Eu(DBM)2HL(2) (40 nm)/LiF (1 nm)/Al (100 nm) emit red light originating from the europium complexes. The device 2 gives the maximum brightness of 455 cd/m(2) at 19.2 V.
