The Kinetically Dominated Overgrowth of Flower-Like Silver Nanostructures and its Application for Surface-Enhanced Raman Scattering

Abstract:

Herein flower-like silver nanostructures with different size and ratio of hexagonal close-packed (HCP) to face-centered cubic (FCC) phase were synthetized. By comparing with the results utilizing different surfactants, the growth process of Ag nanostructures has been investigated. Flower-like Ag nanoparticles containing numerous hot spots could serve as excellent surface-enhanced Raman scattering (SERS) substrates, and the Raman signal of Rhodamine 6G with the concentration as low as 10^-6 M can be recognized.
