Nanoparticles which were prepared by using the aerosol flow reactor method had a well-developed morphology when prepared at sufficiently high temperatures. Hexagonal plate-shaped icosahedral and decagonal particles were observed, and the structure was studied by means of scanning and transmission electron microscopy. The plate-like particles were lamellar-twinned and grew preferentially on the side-faces, via the nucleation of new molecular layers along re-entrant corners. The decagonal multiply-twinned nanoparticles were strained, and exhibited a distinct deviation from cubic symmetry.
