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.
有机长余辉发光体系（OLPLs）在光激发后呈现持久发光，由有机电子供体和受体组成，广泛应用于有机发光二极管（OLEDs）。尽管OLPLs和OLEDs包含非常相似的激子过程，但在OLEDs中从未观察到持久发光。本研究证实了在电激发下存在长余辉发光（LPL）。
