Controlling plasmon-exciton interactions through photothermal reshaping
Opto-Electronic Advances, 2020 We investigated the plasmon-exciton interactions in an individual gold nanorod (GNR) with monolayer MoS2 at room temperature with the single-particle spectroscopy technique.

Surface plasmon polaritons in the ultraviolet region
, 2017 We study a surface plasmon polariton mode that is strongly confined in the transverse direction and propagates along a periodically nanostructured metal-dielectric interface.

Quantum-Coherence-Enhanced Surface Plasmon Amplification by Stimulated Emission of Radiation [PDF]
, 2013 We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium, and show that quantum coherence significantly enhances the generation of surface plasmons.

Advanced Functional Materials, EarlyView.A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

Cascaded second-order surface plasmon solitons due to intrinsic metal nonlinearity
New Journal of Physics, 2013 We theoretically show the existence of cascaded second-order surface plasmon solitons propagating at the interface between a metal and a linear dielectric.

Strong exciton-plasmon coupling in semiconducting carbon nanotubes [PDF]
, 2009 We study theoretically the interactions of excitonic states with surface electromagnetic modes of small-diameter (~1 nm) semiconducting single-walled carbon nanotubes. We show that these interactions can result in strong exciton-surface-plasmon coupling.

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy
Advanced Functional Materials, EarlyView.In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Loss mechanisms of surface plasmon polaritons on gold probed by cathodoluminescence imaging spectroscopy [PDF]
, 2008 We use cathodoluminescence imaging spectroscopy to excite surface plasmon polaritons and measure their decay length on single crystal and polycrystalline gold surfaces. The surface plasmon polaritons are excited on the gold surface by a nanoscale focused

Through Diamond Robust Surface Enhanced Raman Spectroscopy
Advanced Functional Materials, EarlyView.Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...
