Plasmonic ultrafast all-optical switching holds great promise for advancing next-generation optical communication and optical computing technologies. However, achieving subpicosecond all-optical switching with a high on-off ratio remains challenging due to the slow dynamics of electron-phonon scattering in plasmonic materials. Here, we report an innovative method that utilizes the negative signal induced by plasmonic excited hot electrons in the transient spectrum and the positive signal caused by hot electrons excited by off-resonant pumping, both designed at the same wavelength to effectively offset slow dynamics.

Developing highly sensitive and selective detection methods is crucial for environmental and healthcare monitoring. In this study, the chiral and fluorescent signals of L-glutathione-modified gold nanoclusters (L-GSH-Au NCs) were discovered to be responsive to Co, which displayed linear correlations with the concentration changes of Co. Notably, the chiral signal was more sensitive than the FL signal, whose limit of detection (LOD) was calculated to be 0.

The nanoscale ampification of light-matter interactions exhibits profound potential in multiple scientific fields, such as physics, chemistry, surface science, materials science, and nanophotonics. Nonetheless, achieving robust optical mode coupling within cavities faces significant hurdles due to modal dispersion and weak optical field confinement. In this theoretical investigation, we demonstrate the viability of strong coupling between the anapole mode of a slotted silicon nanodisk and the plasmonic modes of an Ag nanodisk dimer at visible light frequencies.
