Abstract
A method for transferring silver nanoparticles from aqueous solution into organic solvents such as toluene or hexane is described. The phase-transfer reagent, tri-n-octylphosphine oxide (TOPO) provides a capping shell around Ag particles that allows concentrating the nanoparticle dispersion in toluene, which is a prerequisite for successful 3D self-assembly. The dispersed particles in toluene are stable for at least six months. Self-assembly of highly concentrated TOPO-capped Ag particle sols results in multilayered mirror-like films on glass substrates.
