The vortex beam with orbital angular momentum (OAM) is a new and ideal tool to selectively excite dipole forbidden states through linear optical absorption. The emergence of the vortex beam with OAM provides intriguing opportunities ...
Nanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that ...
Chemists at RIKEN have discovered why shining light on silver nanoparticles causes oxygen molecules attached to their surfaces to break off. This insight will help researchers design new catalysts that harness light energy.
