Zeolites as host matrix for luminescent carbon dots： a newclass of thermally activated delayed fluorescence materials with 350 ms delayed decay time

摘要

Organic light-emitting diodes （OLEDs） have attractedconsiderable attentions from both academia and industryfor decades because of their potential applications in fullcolor fiat-panel displays and solid state lightings. Since2009 [1], thermally activated delayed fluorescence （TADF）OLEDs have drawn intense attention due to the utilizationof low-cost organic luminogens by harvesting all singletand triplet excitons to theoretically reach 100% internalquantum efficiency.
