向开发新奇金属 nanoparticles (NP ) 和他们的订的数组的最近的研究努力被 plasmonics 的出现激发了。特别地,调节尺寸,形态学,作文和金属 NP 的分离允许我们为特定的应用程序设计 plasmonic 晶体的集体性质。这里我们在场我们自底向上的生长方法的最近的发展并且为如此的 plasmonic 材料的准备表明便利。由在有二维的胶体的晶体上的 micromolding 的联合的金属的物理、化学,或电气化学的免职的实现,有许多形态学的金属性的 NP 能在一个订的格子被创造。准备新奇 plasmonic 晶体能在光学发现应用,光电子,材料科学,察觉到并且生物物理学。
Recent research effort towards developing novel metal nanoparticles (NPs) and their ordered arrays have been motivated by the emergence of plasmonics. In particular, tuning the size, morphology, composition and the separation of metal NPs has allowed us to engineer the collective properties of plasmonic crystals for specific applications. Here we present our recent development of bottom-up growth methods and demonstrate convenience for the preparation of such plasmonic materials. By implementation of physical, chemical, or electrochemical deposition of a metal in combination with micromolding on two-dimensional colloidal crystals, metallic NPs with a variety of morphologies can be created in an ordered lattice. The prepared novel plasmonic crystals could find applications in optics, optoelectronics, materials science, sensing and biophysics.
