摘要：

We introduce Plasmene; in analogy to graphene;as freestanding,one-particle-thick, superlattice sheets of nanoparticles (“meta-atoms”)from the “plasmonic periodic table”, which has implications in many importantresearch disciplines. Here, we report on a general bottom-up self-assemblyapproach to fabricate giant plasmene nanosheets (i.e., plasmene with nanoscalethickness but with macroscopic lateral dimensions) as thin as∼40 nm and as wideas∼3 mm, corresponding to an aspect ratio of∼75 000. In conjunction withtop_down lithography, such robust giant nanosheets could be milled into onedimensionalnanoribbons and folded into three-dimensional origami. Both experimental and theoretical studies reveal that our giant plasmene nanosheetsare analogues of graphene from the plasmonic nanoparticle family, simultaneously possessing unique structural features and plasmon propagationfunctionalities.
