Bulky Counterions: Enhancing the Two-Photon Excited Fluorescence of Gold Nanoclusters
Franck Bertorelle, Christophe Moulin, Antonin Soleilhac +5
Increasing fluorescence quantum yields of ligand-protected gold nanoclusters has attracted wide research interest. The strategy consisting in using bulky counterions has been found…
Observation and analysis of creation, decay, and regeneration of annular soliton clusters in a lossy cubic-quintic optical medium
Albert S. Reyna, Henrique T. M. C. M. Baltar, Emeric Bergmann +5
We observe and analyze formation, decay, and subsequent regeneration of ring-shaped clusters of (2+1)-dimensional spatial solitons (filaments) in a medium with the cubic-quintic (f…
Origin of optical second-harmonic generation in spherical gold nanoparticles: Local surface and nonlocal bulk contributions
Guillaume Bachelier, Jérémy Butet, Isabelle Russier-Antoine +3
The second-harmonic generation of 150 nm spherical gold nanoparticles is investigated both experimentally and theoretically. We demonstrate that the interference effects between di…
