Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Enhanced Light–Matter Interactions With a Single Sn Nanoantenna on Epitaxial Graphene
Advanced Optical Materials, EarlyView.Surface Enhanced Raman Spectroscopy (SERS) is a leading method for surpassing the diffraction limit in analytical detection and exploring light‐matter interactions. In this study, a single plasmonic Sn nanoantenna is employed on epitaxial graphene, achieving extraordinary enhancement of graphene Raman signals.

TADF Emission in Supramolecular Assemblies through Cooperativity and Polymorphism
Advanced Optical Materials, EarlyView.Macroscopic self‐assembled fibers emitting orange color with thermally activated delayed fluorescence (TADF) character are obtained by using encumbered phenyl D‐A linkers in a D‐A‐D configuration. The new dye self‐assembles through a cooperative mechanism into fibers that emit light upon electrical stimulus in solution‐processed organic light‐emitting ...

Advanced Optical Materials, EarlyView.Laser writing converts residual aluminum in MXenes into bright ruby emitters with laser‐like photoluminescence. This approach provides a universal optical tool for mapping material purity. Luminescence sensitivity to temperature, pressure and chemical environment turns synthesis liabilities into assets, enabling the formation of built‐in optical probes

Intracellular Monitoring of Luminescent Ag2S Nanoparticles in Fibroblasts
Advanced Optical Materials, EarlyView.This study investigates the long‐term luminescence behavior of Ag2S quantum dots (AS QDs) with three surface ligands (DTDTPA, 11MUA, PEG) in fibroblasts over 9 days. AS‐PEG showed stable uptake and enhanced NIR‐II emission, while others decreased due to oxidative stress.

Advanced Optical Materials, EarlyView.Fullerene acceptor‐based organic photodetectors show sub‐optimal device performance due to deep trap states originating from undesirable adduct formation between donor and acceptor with unfavorable bulk‐heterojunction morphology. This work demonstrates subphthalocyanine‐based non‐fullerene acceptor (like Cl6‐SubPc) has great potential for trap‐free ...

Advanced Optical Materials, EarlyView.This study explores overlapping charge transport mechanisms in TADF materials and identifies spin‐orbit coupling as the dominant mechanism for triplet‐to‐singlet transition in carbazole‐based cyanoarene emitters. Computational investigations reveal a second spin‐orbit‐coupling‐mediated reverse intersystem crossing pathway, significantly enhancing the ...
