金属纳米壳层是一种新型的复合纳米粒子，其光学共振可以以可控的方式“设计”。通过改变核和壳的相对尺寸，这些纳米颗粒的光学共振可以在数百纳米的波长上变化，跨越可见光并进入光谱的红外区域。我们报道了一种基于分子自组装和胶体还原化学制备金属纳米壳复合纳米粒子的一般方法。(C)1998 Elsevier Science B.V.保留所有权利。
Metal nanoshells, consisting of a dielectric core with a metallic shell of nanometer thickness, are a new, composite nanoparticle whose optical resonance can be "designed in" in a controlled manner. By varying the relative dimensions of the core and shell, the optical resonance of these nanoparticles can be varied over hundreds of nanometers in wavelength, across the visible and into the infrared region of the spectrum. We report a general approach to the making of metal nanoshell composite nanoparticles based on molecular self-assembly and colloid reduction chemistry. (C) 1998 Elsevier Science B.V.
