Abstract
Dopant and non-dopant OLEDs were fabricated for testing four TADF emitters, having EL of blue to greenish blue color. The tetraphenyibenzene (4Ph)-containing emitters have been demonstrated having a higher light outcoupling efficiency for dopant devices and a superior IQEfor the non-dopant devices. ? 2019 SID.
