Afterglow Organic Light‐Emitting Diode

Advanced Materials, 2015
An afterglow organic light-emitting diode (OLED) that displays electroluminescence with long transient decay after it is turned off is demonstrated. This OLED exhibits blue and green dual emission originating from fluorescence and phosphorescence, respectively. A phosphorescence lifetime of 4.3 s is achieved.

Modulating Tri‐Mode Emission for Single‐Component White Organic Afterglow

Angewandte Chemie International Edition, 2021
AbstractAchieving single‐component white organic afterglow remains a great challenge owing to the difficulties in simultaneously supporting long‐lived emissions from varied excited states of a molecule for complementary afterglow. Here, an extraordinary tri‐mode emission from the radiative decays of singlet (S1), triplet (T1), and stabilized triplet ...

Manipulation of Organic Afterglow in Fluoranthene‐Containing Dopant‐Matrix Systems: From Conventional Room‐Temperature Phosphorescence to Efficient Red TADF‐Type Organic Afterglow

Chemistry – A European Journal, 2023
AbstractIt remains challenging to fabricate highly‐efficient and long‐lived organic afterglow materials, especially in the case of red afterglow systems. Here we develop advanced charge transfer (CT) technology to boost afterglow efficiency and lifetimes in fluoranthene‐containing dopant‐matrix systems.
