Plasmon coupling in nanorod assemblies: Optical absorption, discrete dipole approximation simulation, and exciton-coupling model
Article Abstract:
A study explores the orientational dependence of plasmon coupling in assemblies of anisotropic plasmonic nanoparticles. Findings demonstrate that the solution assembly of nanorods induced by the addition of sodium citrate results in the blue-shift of the longitudinal nanorods plasmon band, and a red-shift of the transverse plasmon band.

The optically detected coherent lattice oscillations in silver and gold monolayer periodic nanoprism arrays: The effect of interparticle coupling
Article Abstract:
The optically detected laser-induced coherent phonon oscillation of monolayers of periodic arrays of prismatic-shaped silver and gold nanoparticles is studied using femtosecond transient spectroscopy. For both gold and silver nanoparticles, the surface plasmon absorption maximum is found to depend linearly on size.

Size-dependent ultrafast electronic energy relaxation and enhanced fluorescence of copper nanoparticles
Article Abstract:
An investigation is conducted on the size-dependent ultrafast electronic energy relaxation in the conduction band of copper nanoparticles in colloidal solution by using femtosecond time-resolved transient spectroscopy. Results show that how electron energy relaxation has clear size dependence.
