摘要

采用HDT1和36Me-HDT1两个热激活延迟荧光（TADF）发射体制备了高效的非掺杂蓝绿色到绿色热激活延迟荧光（TADF） oled，最大外量子效率（EQEmax）值分别为16.5%和21.0%。单堆叠，三色，暖白色高荧光oled也证明了EQEmax为12.1%。

Efficient host-free delayed fluorescence organic light-emitting diodes†

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%.
