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 ...

High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
