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 ...

Advanced Optical Materials, EarlyView.Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.
