High Performance NIR OLEDs with Low Efficiency Roll‐Off by Leveraging Os(II) Phosphors and Exciplex Co‐Host

Near‐infrared (NIR) organic‐light emitting devices (OLEDs) with high radiance are useful for applications including invisible marking, communication, and biomedical imaging. However, performances of NIR OLEDs are typically limited by their severe efficiency roll‐offs at high current density. Herein,...
