Organic afterglow
Witryna12 lut 2024 · Here, we demonstrate that the organic afterglow can be enhanced dramatically by thermally activated processes to release the excitons on the stabilized triplet state (T 1 *) to the lowest triplet state (T 1) and to the singlet excited state (S 1) for spin-allowed emission. Designed in a twisted donor-acceptor architecture with small … Witryna9 wrz 2024 · Purely organic afterglow (POA) originating from the slow radiative decay of stabilized triplet excited states has shown amazing potential in many fields. However, …
