Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

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 ...

Enhanced Scintillation with Uncorrelated TL and OSL Signals in LiCaAlF6:Eu Nanoparticles Enables Unprecedented Multimodal Radiation Dosimetry

Advanced Optical Materials, EarlyView.
The graphical abstract illustrates the coexistence of independent OSL and TL signals, demonstrating that the material preserves TL information even after complete OSL zeroing, enabling a dual dosimetric readout within the same material. Abstract The development of multimodal dosimeters capable of preserving independent luminescent signals is a ...

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

Advanced Optical Materials, EarlyView.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.
