Efficient sky-blue organic light-emitting diodes (OLEDs) employing thermally activated delayed fluorescence (TADF) display a three orders of magnitude increase in lifetime, which is superior to those of controlled phosphorescent OLEDs used in this study. The combination of electro-oxidation and photo-oxidation of the TADF emitters in their triplet excited-states is suppressed through molecule design and device engineering.
高效天蓝光致发光二极管（OLED）采用热激活延迟荧光（TADF）技术，寿命延长了三个数量级，优于本研究中使用的受控磷光 OLED。通过分子设计和器件工程抑制了 TADF 发射器三重态激发态的电氧化和光氧化的结合。
