Preparation and study of polyacryamide-stabilized silver nanoparticles through a one-pot process

Article Abstract:

A one-pot route was used to synthesize stable well-dispersed silver colloids stabilized by polyacrylamide on a large scale. The obtained colloids were the mixture of Ag and Ag2O nanoparticles and the presence of silver oxide layers on the nanoparticle surface resulted in the broadening of the surface plasmon band of silver nanoparticles.

Tuning of copper nanocrystals optical properties with their shapes

Article Abstract:

Copper nanocrystals are obtained by chemical reduction of copper ions in mixed reverse micelles. By using UV-Visible spectroscopy and numerical optical simulations, it is demonstrated that the relative proportions of spheres and nanodisks tune the optical properties.
