Unveiling quasi-dark surface plasmon modes in Au nanoring cavities by cathodoluminescence

Scientific Reports, 2017
Spectral resolving and imaging surface plasmon modes in noble metal nanostructures are important for applications in nanophotonics. Here, we use cathodoluminescence (CL) spectroscopy to excite and probe quasi-dark plasmon modes of Au nanoring cavities ...

Plasmonic Focusing of a High-Order Cylindrical Vector Beam for On-Chip Detection

Photonics
We investigate the interaction between cylindrical vector beams (CVBs) and metallic annular structures. The mechanisms for plasmonic focusing and field distributions are studied both analytically and numerically. We demonstrate that the focusing patterns

Unveiling size-selective host-guest interaction of photoresponsive nanorings with carbon nanotubes and fullerenes

Scientific Reports
The intricate host-guest chemistry of π-conjugated nanorings, such as [6]Cycloparaphenyleneacetylenes ([6]CPPAs) and [6]Cycloparaphenylenediazenes ([6]CPPDs), has emerged as a focal point in the study of advanced materials due to their versatile ...
