文摘

Seed based synthesis of nano gold particles with decahedral and truncated tetrahedral morphologies. Morphological features explained based on supergroup symmetry of the seed. Triangular streaks around the Bragg spots correlated with shape effect. Forbidden reflections 1/3{422} from truncated tetrahedral nanoparticles understood in terms of intrinsic fault. Decrease in lattice parameter was corroborated in terms of aforesaid fault.
