Abstract

Face centered cubic (FCC) single crystal silver nanoparticles(NPs) of nearly monodispersed particle size of 12nm were prepared by simple ripening multi-twined particles (MTP). The product yield was nearly 100% and growth mechanism was considered to be similar to Ostwald ripening but utilize chemical potential difference between MTP and FCC NPs. Controlling the ratio between defectless and defective particles before ripening by controlling kinetics of particle generation stage, it was possible to control the final defectless particle size from 7-18 nm maintaining almost 100% product yield.
