Abstract: Abstract: A simple, bilayered, red phosphorescent organic light-emitting device featuring a doubly-doped emitting layer comprising of the novel hole-transporting host DTAF, the electron-transporting host 27SFBI, and the emitter Os(bpftz)2(PPhMe2)2 covering the interfacial region provides an unusually high current of ca. 1560 mA cm−2 at 8.5 V, a maximum brightness of 32 700 cd m−2, external quantum efficiencies as high as 12.3% (10.9% at 1000 cd m−2), and a power efficiency of 13.5 lm W−1. This concise device architecture is very cost-effective and competitive for practical applications.
