| Abstract: Highly ordered arrays of 3D faceted nanoparticle supercrystals are formed
by self-assembly with controlled nanoparticle packing and unique facet
dependent optical property by using a binary solvent diffusion method.
The binary diffusion results in supercrystals whose size and quality are
determined by initial nanoparticle concentration and diffusion speed. The
supercrystal solids display unique facet-dependent surface plasmonic and
surface-enhanced Raman characteristics. The supercrystals have potential
applications in areas such as optics, electronics, and sensor platforms. |
