摘要	A series of terbium complexes with different structures revealed different carrier-transport and photophysical properties. Complex A [tris(1-phenyl-3-methyl-4-isobutyl-5-pyrazolone)bis(triphenyl phosphine oxide), Tb(PMIP)(3)(TPPO)(2)] had overly strong electron-transport properties, complex B [Tb(PMIP)(3)(EtOH)(H2O)] mainly revealed hole-transport properties, and complex C [tris(1-phenyl-3-methyl-4-(2-ethylbutyryl)-5-pyrazolone) triphenyl phosphine oxide, Tb(eb-PMP)3(TPPO)] showed both electron- and hole-transport properties. Their PL intensity ratio was A-B-C = 2.6:1:1.2. The eletroluminescence (EL) performances (brightness and peak power efficiency) achieved from complexes A, B, and C were 9600 cd/m(2) and 5.21 lm/W, 2800 cd/m(2) and 2.61 lm/W, and 12000 cd/m(2) and 11.3 lm/w, from device configurations of ITO/TPD-B-A-AlQ-Mg0.9Ag0.1-Ag (20:20:50:30:200:80 nm), ITO/TPDB-BCP-AlQ-Mg0.9Ag0.1)-Ag (40:30:20:20:200:80 nm), and ITO/NPB-C-BCP-AlQ-Mg0.9Ag0.1-Ag (10:50:20:40:200:80 nm), respectively. Results indicated that for a given terbium complex, balanced carrier injection and a well-confined recombination zone are crucial to obtaining maximum EL performance. More important, if this premise is satisfied, for different complexes, the higher the PL quantum yield the complex shows, the greatly improved the EL performance will be.
