摘要 介绍了一种由无序树形结构构成的超材料的自下而上化学制备方法,这种超材料可工作在可见光频段。当树形结构的直径为500nm时,这种金纳米树形结构阵列超材料分别在470,540,670 nm频段出现透射通带,这种超材料也可在可见光频段实现平板聚焦,有益于对可见光频段超材料的研究。 We demonstrate a visible light frequencies metamaterials (MMs) composed of disordered dendritic cells, and a novel bottom-up approach to fabricate the MMs using chemical method. When the diameter of the cell is about 500 nm, the as-prepared gold dendritic nanostructural array exhibits passbands at wavelength of 470, 540 and 670 rim, respectively. The MMs also realize slab focusing effect at visible wavelength. It would be significant to accelerate the development of visible frequencies MMs.
