The feasibility of adopting bis[2-(4-tert-butylphenyl) benzothIazolato-N,C-2'] iridium (acetylacetonate) [(t-bt)2Ir(acac)] in the direct hole-injection structure was investigated. Yellow phosphorescent organic light-emitting diodes based on (t-bt)2Ir(acac) with this structure were fabricated. The efficiencies of these diodes reached 27.51 lm/W and 53.33 cd/A at a brightness of 45 891 cd/m2. The realisation of these excellent efficiencies is ascribed to the characteristics of (t-bt)2Ir(acac) and the direct hole-injection structure.
