Characterization of Ag Nanoparticle Superlattice Structure Prepared Using Two Carboxylic Acids
Abstract:One-step hydrothermal process is introduced for the synthesis of highly ordered self-assembled Ag nanoparticles. Ag nanoparticles with same diameter and narrow size distribution are synthesized in the presence of the mixture of two capping molecules, the combination of sodium oleate and aromatic carboxylic acid. Self-assembled 3D superlattice structures of Ag nanoparticles are synthesized in aqueous system without any post-procedure. Effects of aromatic carboxylic acid to sodium oleate and the nature of interaction between nanoparticles in superlattices are characterized with TEM examinations and FT-IR spectra.
