Plasmon-Enhanced Photocurrent from Photosystem I Assembled on Ag Nanopyramids [PDF]

, 2018
Plasmonic metal nanostructures have been known to tune optoelectronic properties of fluorophores. Here, we report the first-ever experimental observation of plasmon-induced photocurrent enhancements from Photosystem I (PSI) immobilized on Fischer ...

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Plasmon transport and its guiding in graphene

New Journal of Physics, 2014
Transport of plasmons in graphene has been investigated by time-resolved electrical measurements. We demonstrate that the velocity v (or the refractive index $\propto \;{{v}^{-1}}$ ) and the characteristic impedance Z of the plasmon mode can be tuned ...

Transformation plasmonics [PDF]

Nanophotonics, 2012
Abstract Surface plasmons polaritons (SPPs) at metal/dielectric interfaces have raised lots of expectations in the on‐going quest towards scaling down optical devices. SPP optics offers a powerful and flexible platform for real two‐dimensional integrated optics, capable of supporting both light and electrons. Yet,

Surface plasmon-coupled emission for applications in biomedical diagnostics [PDF]

, 2009
Surface plasmon-coupled emission (SPCE) is a phenomenon whereby the light emitted from a fluorescent molecule can couple into the surface plasmon of an adjacent metal layer resulting in highly directional emission in the region of the surface plasmon ...

Plasmon-Mediated Chiroptical Second Harmonic Generation from Seemingly Achiral Gold Nanorods [PDF]

, 2021
Throughout nature, simple rules explain complex phenomena, such as the selective interaction of chiral objects with circularly polarized light. Here, we demonstrate chiroptical signals from gold nanorods, which are seemingly achiral structures.

Spin Injection Of Exciton–Polaritons With Halide Perovskites At Room Temperature

Advanced Functional Materials, EarlyView.
A monolithic Tamm‐plasmon microcavity embedding a two‐dimensional halide perovskite enables room‐temperature spin injection of exciton‐polaritons under quasi‐resonant optical excitation. Polarization‐resolved spectroscopy reveals partial preservation of the injected spin in the lower polariton branch, while bare excitons remain fully depolarized.
