Abstract

By chemically modifying the nucleation burst that generates monodisperse FePt nanocrystals, a mixture of Pt and Fe_xPt_1-x nanoparticles forms during a one-pot reaction that includes a small amount of Cu as a catalyst; size-selective precipitation yields a bi-disperse population of Fe_xPt_1-x nanoparticles, which can assemble into high-quality AB₂, AB₅, and AB₁₃ superlattice structures.
