Qisheng Zhang,Bo Li,Shuping Huang,Hiroko Nomura,Hiroyuki Tanaka,Chihaya Adachi,Chihaya Adachi +6 more
TL;DR: In this article, a blue organic light-emitting diodes that harness thermally activated delayed fluorescence was realized with an external quantum efficiency of 19.5% and reduced roll-off at high luminance.
Journal ArticleDOI
Nearly 100% Internal Quantum Efficiency in Undoped Electroluminescent Devices Employing Pure Organic Emitters
Qisheng Zhang,Daniel Tsang,H. Kuwabara,Yasuhiro Hatae,Bo Li,Takehiro Takahashi,Sae Youn Lee,Takuma Yasuda,Chihaya Adachi +8 more
TL;DR: Blue and green organic light-emitting diodes containing a hole-transport layer, an undoped TADF emissive layer, and an electron-trans transport layer achieve maximum external quantum efficiencies of 19%, which is comparable to the best doped OLEDs.
