This study reports the long-range superstructures of oriented attached PbSe nanocrystals in different dimensions, including 1D linear and 3D structures. The research not only demonstrates stronger design capability for PbSe superstructures, but also reveals important information about the interfacial behavior during self-assembly of PbSe nanocrystals.
We report the 1D linear, 2D square, 2D honeycomb, and 3D topo-epitaxy long-range superstructures of oriented attached PbSe NCs. In particular, we discovered novel 1D linear and 3D superstructures, which implied different formation mechanisms compared with the PbSe superstructures previously reported. Our study not only demonstrates stronger design capability for oriented-attached PbSe superstructures, but also reveals important information about the interfacial behavior of the PbSe NCs during the self-assembly. Novel one-dimensional linear and 3-dimensional topo-epitaxy superstructures were prepared from PbSe nanocrystals dispersed in toluene by oriented attachment-assisted self-assembly at the ethylene glycol/Ar.
