In this study, we attempted to present a direct synthesis of narrowly dispersed silver nanoparticles in highly concentrated organic phase (> 2 M) without use of a size-selection process The fully organic phase system contains silver nitrate as a silver precursor, alkyl amine as a media dissolving silver salt, alkanoic acid as a capping molecule, hydrocarbon solvent as a media, and reducing reagent. Even using only generic chemicals, monodispersed silver nanocrystals with size of 7 nm were easily synthesized at 100 gram-scale in 1 liter reactor. Also, systematic studies revealed that silver nanoparticles synthesized through ligand exchange method were stabilized through bidentate bridging of carboxyl group in alkanoic acid.
