　　Bimetallic nanocrystals could be used as multifunctional nanocrystals by coupling the optical or catalytic properties of one metal with those of another metal.Nanocrystals with concave faces have attracted great interest because of the high-index facets on surfaces.High resolution transmission electron microscopy (HRTEM), aberration (Cs) corrected high angle angular dark field (HAADF)-scanning transmission electron microscopy (STEM) with energy dispersive x-ray spectroscopy (EDS) have been proven to be an unique and effective site-specific analysis tool at atomic and nano scale to study the crystal structure and chemistry of nanocrystals.
