Abstract

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.

Keywords: electroluminescence; intermolecular interactions; light-emitting diodes; nonradiative decay; phosphorescence.
