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

Interactions of Nitrogen‐Vacancy Centers in Diamond with Electron Beams: Implications for Quantum Sensing and Photoluminescence Stability

open access: yesAdvanced Optical Materials, EarlyView.
Under the influence of an electron beam, the photoluminescence (PL) and quantum sensing stability of nitrogen‐vacancy (NV) centers in fluorescent nanodiamonds (FNDs) change. This work elucidates structural and functional changes induced by the electron beam in FNDs and identifies imaging conditions to preserve NV properties and offers a pathway for top‐

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 ...
