White Organic LED with a Luminous Efficacy Exceeding 100 lm W−1 without Light Out-Coupling Enhancement Techniques
Sheng-Fan Wu,Si-Hua Li,Ya-Kun Wang,Chen-Chao Huang,Qi Sun,Jiao-Jiao Liang,Liang-Sheng Liao,Man-Keung Fung +7 more
TL;DR: In this paper, an ultra-efficient white organic light-emitting diodes (OLEDs) is discussed based on a newly designed thermally activated delayed fluorescent exciplex host, which delivers an unusually high forward-viewing LE of 105.0 lm W−1 and external quantum efficiency (EQE) ηext of ≈30% (without using any optical outcoupling techniques).

Highly Efficient White Organic Light-Emitting Diodes with Ultrathin Emissive Layers and a Spacer-Free Structure.
TL;DR: The present work demonstrated spacer-free and simple-structured white-emitting OLEDs with a good device performance and efficiencies, which are the highest ever reported for OLEDs fabricated with the UEML approach.
Thermally Activated Delayed Fluorescence Material as Host with Novel Spiro‐Based Skeleton for High Power Efficiency and Low Roll‐Off Blue and White Phosphorescent Devices
Ya-Kun Wang,Qi Sun,Sheng-Fan Wu,Yi Yuan,Qian Li,Zuo-Quan Jiang,Man-Keung Fung,Liang-Sheng Liao +7 more
TL;DR: In this paper, a novel thermally activated delayed fluorescence type blue host Tri-o-2PO was successfully developed, which achieved high power efficiency and reduced the operating lifetime of blue organic light-emitting diodes.

Management of excitons for highly efficient organic light-emitting diodes with reduced triplet exciton quenching: synergistic effects of exciplex and quantum well structure
Si-Hua Li,Sheng-Fan Wu,Ya-Kun Wang,Jiao-Jiao Liang,Qi Sun,Qi Sun,Chen-Chao Huang,Jing-Cun Wu,Liang-Sheng Liao,Liang-Sheng Liao,Man-Keung Fung,Man-Keung Fung +11 more
TL;DR: In this article, the authors proposed a new strategy by synergistically incorporating the so-called interface-exciplex (i-Exc) with a multi-quantum-well structure (MQW), achieving an extremely low voltage of ∼2.8 V at a current density (j) of 0.2 mA cm−2.
