Multi‐Level Hybrid Anti‐Counterfeit Labels via Solid‐State Dewetting Under Spatial Confinement
Advanced Materials Technologies, EarlyView.This study presents a hybrid encoding approach combining deterministic patterns fabricated by photolithography and stochastic features formed by the solid‐state dewetting of silver films under strong confinement at the micrometer and nanometer length scales.

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Precision‐Engineered Plasmonic Nanostar Arrays for High‐Performance SERS Sensing
Advanced Optical Materials, EarlyView.Highly ordered and dose‐controlled arrays of gold nanodiscs are created using the dots‐on‐the‐fly EBL technique and subsequently converted into nanostar arrays. This technique unlocks the reproducible and robust fabrication of highly efficient SERS substrates. Abstract Surface‐enhanced Raman scattering (SERS) spectroscopy has emerged as a powerful tool

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

Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface
Advanced Optical Materials, EarlyView.Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems
Advanced Optical Materials, EarlyView.The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...
