Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...
