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 ...

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 ...

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

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.
