Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

TADF Emission in Supramolecular Assemblies through Cooperativity and Polymorphism

open access: yesAdvanced 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 ...

Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

open access: yesAdvanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

Spectrally Adjustable Narrowband Photonic Device Based on Heat‐Driven Amorphous‐to‐Crystal Transformation of Si

open access: yesAdvanced Photonics Research, EarlyView.
The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...
