Show more >Near-infrared (NIR) narrowband organic photodetectors (OPDs) can be essential building blocks for emerging applications including wireless optical communication and light detection, but further improvement of their performances remains to be a great challenge. Herein, a light manipulation strategy combining solutionprocessable gold nanorings (AuNRs)-based hole transporting layer (HTL) and an optical microcavity is proposed to achieve highperformance NIR narrowband OPDs. Optical microcavities with a Fabry-Peŕot resonator structure, guided by theoretical simulation, are coupled with PM6:BTP-eC9-based OPDs to exhibit highly tunable NIR selectivity. The further integration of AuNRs array with NIRcustomized localized surface plasmon resonance in the HTL of the NIR narrowband OPDs enables evident NIR absorption enhancement, yielding a specific detectivity exceeding 10 13 Jones (1.5 × 10 12 Jones, calculated from noise spectral density) at 820 nm, along with a finely selective photoresponse (full width at halfmaximum of 80 nm) and a 3-fold increase in photocurrent intensity. Finally, the practical application of our OPDs is demonstrated in an NIR communication system. These results reveal the great potential of an appropriate optical design for developing highly performing NIR narrowband OPDs.Show less >
