Fluorescent and Phosphorescent Emitting Layers by Utilizing a Triplet Harvesting in Hybrid White Organic Light-Emitting Diodes
Triplet harvesting is explained via non-radiative triplet excitons for efficient exciton energy transfer from the blue fluorescent emitters to the red and green phosphorescent emitters, where they can be decayed radiatively. The mixed TCTA:TPBi plays an important role as a charge carrier because it regulates the distribution of excitons and hole–electron recombination zone.
