Twin free face centered cubic (FCC) silver nanoparticles of nearly monodispersed particle size were prepared by simple ripening of multi-twined particles (MTP). The particle size was 12nm and the product yield was almost 100%. The growth mechanism was considered to be similar to Ostwald ripening except that it utilized chemical potential gap between MTP and FCC NPs. The kinetics of particle generation stage affected the final particle size and the possibility of controlling the final defectless particle size from 8-17 nm maintaining almost 100% product yield was achieved. The particle generation stage kinetics is considered to determine the ratio between FCC and MTPs before ripening, and consequently the final particle size.
