Three-dimensional structure of nanocrystals from high-energy x-ray diffraction and atomic pair distribution function analysis

Abstract

The atomic Pair Distribution Function (PDF) analysis and high-energy x-ray diffraction are introduced as a tool for determining the three-dimensional structure of nanocrystalline materials. The great potential of this experimental approach is demonstrated with results from successful studies on (Polyaniline)xV2O5nH2O nanocomposites and dendrimer stabilized gold nanoparticles. We find that (Polyaniline)xV2O5nH2O has a lamellar-type structure wherein polymeric chains are sandwiched between double layers of V-O6 octahedra. Gold nanoparticles possess a distorted face centered cubic-type structure with the degree of distortion increasing with the decrease in particle's size.
