Journal of the Society for Information Display, EarlyView.Two complementary molecular design strategies are proposed to independently enhance operational stability and device efficiency in MR‐TADF OLEDs. Strengthening the cationic bond dissociation energy (BDEf+) improves intrinsic molecular robustness and prolongs device lifetime, although a PSF‐based efficiency‐oriented design with high molar absorption ...

Interference‐Induced Cavity Resonances and Imaginary Rabi Splitting
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Coupling of a two‐level emitter to (a, b) a single‐mode resonance with a Lorentzian spectral density, and (c, d) a two‐mode cavity with a more complex spectral density. This work reveals a new polaritonic regime beyond the single‐mode description, emerging from emitter interaction with the interference‐induced resonance associated with the Fano ...

Ultrasensitive Tunable Terahertz Sensor via Critical Coupling‐Enhanced Fano Resonance
Nanophotonics, Volume 15, Issue 9, 13 May 2026.This work presents a hybrid terahertz sensor via the combination of graphene‐strip metasurface, cavity resonance, and gold film polaritons. The sensor achieves critical coupling with an ultrahigh‐Q resonance and tunable FOM with stable high sensitivity via gate voltage regulation, exhibiting excellent performance for on‐chip integrated biochemical ...
