Abstract

Efficient non-doped bluish-green to green thermally activated delayed fluorescence (TADF) OLEDs are fabricated with two TADF emitters, namely HDT1 and 36Me-HDT1, achieving maximum external quantum efficiency (EQE_max) values of 16.5% and 21.0%, respectively. Single-stack, three-color, warm-white hyperfluorescent OLEDs are also demonstrated with an EQE_max of 12.1%. © 2025 The Royal Society of Chemistry.
