| Popis: | Morphological changes were studied in spherical silver nanoparticles (NPs) prepared using laser ablation of silver plates in an acetone–water mixed solution after laser irradiation. When reagent solutions were left for 1–14 days after laser irradiation, Ag nanocrystals (NCs) involving cubes formed spontaneously. Results show that laser irradiation and acetone are unnecessary for cube formation, but they enhance the cube formation efficiency because of the spherical NP size reduction. These findings suggest that cube formation occurs via an atom transportation process resembling that which occurs in the ripening process of NPs prepared using chemical reduction methods. |
