Self-filtering narrowband high performance organic photodetectors enabled by manipulating localized Frenkel exciton dissociation

摘要

Chemical structures of Y6, NT812, s-4FPA and PFN-Br. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) depth profile through the prepared film. Reconstructed three-dimensional negative ion images (100 μm × 100 μm area) of C H F N O S , SN and their composite from a depth profile of the prepared film. Basic device structure of self-filtering (SF) narrowband organic photodetector (OPD). External quantum efficiency (EQE) curves of the SF-narrowband OPD and reference device under −0.1 V bias.
