有机长余辉发光系统（OLPL）在光激发后表现出持久发光，由有机电子供体和受体组成，广泛用于有机发光二极管（OLED）。尽管 OLPL 和 OLED 包含非常相似的激子过程，但在 OLED 中从未观察到持久发射。这项研究证实了电激发下长余辉发光（LPL）的存在。
Organic long‐persistent luminescent systems (OLPLs) exhibiting long‐lasting emission after photoexcitation consist of organic electron donors and acceptors, that are widely used in organic light‐emitting diodes (OLEDs). Although OLPLs and OLEDs include very similar excitonic processes, long‐lasting emission has never been observed in OLEDs. This study confirms the presence of long‐persistent luminescence (LPL) under electrical excitation.
