Co-assembly of shaped nanoparticles into a two-dimensional iso-tropic mesophase†
Abstract
Binary nanoparticle superlattices (BNSLs) enable the construction of new mesomaterials by combining the properties of two nanoparticle building blocks. We demonstrate two-dimensional (2D) BNSLs from silver nanocubes and gold nanospheres, analyzing their interparticle and orientational orders. Our experimental mesophase diagram identifies an isotropic phase that serves as a transition state to others.
