Abstract:
Composition for use in an organic light-emitting device, the composition having a fluorescent light-emitting material and a triplet-accepting material subject to the following energetic scheme: 2×T1A>S1A>S1E, or T1A+T1E>S1A>S1E in which: T1A represents a triplet excited state energy level of the triplet-accepting material; TIE represents a triplet excited state energy level of the light-emitting material; S1A represents a singlet excited state energy level of the triplet-accepting material; and S1E represents a singlet excited state energy level of the light-emitting material; and in which light emitted by the composition upon excitation includes delayed fluorescence.
