Improved Disorder Resilience in Small‐Footprint Photonic Cavities with Periodicity Breaking
Advanced Optical Materials, EarlyView.Compact photonic crystal cavities with engineered aperiodicity are demonstrated to sustain high quality factormodes and enhanced reproducibility within a minimal footprint. Combining numerical optimization and near‐field measurements, the study reveals how controlled periodicity breaking improves disorder resilience, offering a robust and scalable ...

Advanced Optical Materials, EarlyView.This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Advanced Optical Materials, EarlyView.Chiroptical properties of DNA‐stabilized silver nanocluster (DNA)2[Ag16Cl2]8+ are presented in linear and nonlinear regime. These water‐soluble, NIR‐emitting nanoprobes demonstrate exceptionally high two‐photon circular dichroism and circularly polarized luminescence brightness.

Versatile Gasochromic Hydrogen Detection via Supraparticle‐Based Applied Composite Materials
Advanced Optical Materials, EarlyView.Silica‐platinum‐resazurin supraparticles are embedded into PMMA to form suprabeads and thin films. The thereby obtained indicators change color from purple to pink to colorless on hydrogen exposure. The indicator systems are tested under various environmental conditions, and their performance is related to their microscopically visualized structure ...

Excitonic Landscapes in Monolayer Lateral Heterostructures Revealed by Unsupervised Machine Learning
Advanced Optical Materials, EarlyView.Hyperspectral photoluminescence data from graded MoxW1 − xS2 alloys and monolayer MoS2–WS2 lateral heterostructures are analyzed using unsupervised machine learning. The combined use of PCA, t‐SNE, and DBSCAN uncovers distinct excitonic regions that trace how composition, strain, and defects modulate optical responses in these 2D materials.
