Anisotropic Assembly of Ag Nanoprisms

Abstract

The Ag nanoprisms with controlled arrangements show distinct optical, crystallographic, and surface-enhanced Raman scattering properties depending on their orientation in the assemblies, demonstrating that the controlled assembly of anisotropic nanostructures can be utilized as a powerful tool for studying their physicochemical properties and for the creation of new classes of functional materials.

Two-Step Photonic Reduction of Controlled Periodic Silver Nanostructures for Surface-Enhanced Raman Spectroscopy

“…7b) show an overwhelmingly intensive diffraction peak from the (111) lattice plane with two very weak peaks from the (200) and (311) planes of FCC Ag. A similar result has been reported by Bae et al [22] who assembled Ag nanoprisms by a wet chemical method. It is notable that the intensity ratios between the (111) and (200) diffraction peaks following 615-nm reduction is 0.06, lower than the 0.17 observed with 365-nm reduction.…”

Laser-Induced Formation and Disintegration of Gold Nanopeanuts and Nanowires

“…17,18 Various shapes such as nanorods, nanoprisms, nanocubes, and nanocages have been synthesized by using the chemical methods. [19][20][21][22][23] Alternative to such chemical approach, lasers may be used to produce nanocrystals or to control the size and shape of preformed nanoparticles. Lasers are particularly advantageous because they provide an intense burst of energy in a short period of time, which may allow one to produce a unique shape of nanoparticles that cannot be achieved in the conventional wet chemistry.…”
