等离子体激元的出现激发了近年来对新型金属纳米粒子及其有序阵列的研究。特别是，调整金属纳米颗粒的大小，形态，组成和分离使我们能够设计用于特定应用的等离子体晶体的集体性质。在这里，我们提出了我们最近的发展自下而上的生长方法，并证明方便的制备等离子体材料。通过在二维胶体晶体上实施金属的物理、化学或电化学沉积结合微成型，可以在有序晶格中产生具有各种形态的金属NP。所制备的等离子体激元晶体在光学、光电子学、材料科学、传感和生物物理学等方面有着广泛的应用前景。
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.
