Effects of Varying Deposition Rates of a Carbazole and Triazine Derivative on Its Tunable Emission and Charge‐Transporting Properties Beneficial for Efficient Red Electroluminescent Devices

open access: yesAdvanced Optical Materials, EarlyView.
The highly efficient and ultrafast thermally activated delayed fluorescence (TADF) behavior of the bipolar derivative of carbazole and triazine stems from the high‐lying triplet states (hot TADF), which has a direct impact on the overall triplet harvesting of guest‐host mixtures.

Synergistic Effect of Compositional Engineering and Graded Heterojunction Formation in Tin‐Halide Perovskites for Near‐Infrared Photodetectors

open access: yesAdvanced Optical Materials, EarlyView.
The compositional engineering of Sn‐halide perovskite with alkylammonium chloride, combined with graded heterojunction formation using fullerene, is shown to significantly enhance crystallinity and reduce trap densities. Consequently, the resulting photodetectors achieve a 63.4% external quantum efficiency and a specific detectivity of 1.38 × 1011 ...

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

open access: yesAdvanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.
