Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

π‐Bridge Engineering of Nonfullerene Acceptors for Organic Photodiodes: Extension of the Near Infrared Response Beyond 1200 nm

open access: yesAdvanced Functional Materials, EarlyView.
A π‐bridge engineering strategy enhances intramolecular charge transfer, enabling non‐fullerene acceptors to extend near‐infrared absorption beyond 1200 nm. The resulting organic photodiodes exhibit high detectivity and fast response. These high‐performance devices demonstrate practical potential in photoplethysmography and optical wireless ...

Photoluminescent UV Light Modulation via Anisometric Carbon Nanodots for UV–Visible Shutter and UV Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.
