How does a gold nanorod melt?
Article Abstract:
Structural transformation of gold nanorod is investigated by high-resolution transmission electron microscopy after they are exposed to low-energy fremosecond and nanosecond laser pulses in colloidal solution. It is concluded that high-resolution TEM revealed that point planar defects are present in gold nanorods after laser irradiation although the as-prepared nanorods are detect-free.

Ultrafast electron relaxation dynamics in coupled metal nanoparticles in aggregates
Article Abstract:
The effect of aggregation in gold nanoparticles on their ultrafast electron-phonon relaxation dynamics measured by femtosecond transient absorption pump-probe spectroscopy is reported. Results strongly suggest the presence of intercolloid electronic coupling within the nanoparticle aggregates, besides the well-known dipolar plasmon coupling.

Picosecond self-induced thermal lensing from colloidal silver nanodisks
Article Abstract:
The static and ultrafasttime-resolved pump-probe spectroscopy is used to study the thermal relaxation dynamics of silver nanodisks. A large increase in the bleach intensity at long delay times (greater than 20 ps) after femtosecond laser excitation has been observed due to the thermal lensing phenomenon.
