A hybrid pattern with micropatterned nanoarray of Au-Pt core-shell particles in the background of Au nanoarray was fabricated via an approach combining photolithography, block copolymer micelle nanolithography, and controlled seed growth. Two pertinent patterns were also obtained: one is a hexagonal nanopattern of Au-Pt bimetallic nanodots with controlled thickness of Pt shells, and the other is an interlaced pattern of Pt microsheets and Au nanoarrays. We thus present a platform to generate regular micro-nano patterns of one or more than one metal on a solid surface.
通过结合光刻、嵌段共聚物胶束纳米光刻和控制种子生长的方法，制备了具有 Au-Pt 核壳粒子微图案纳米阵列背景的混合图案。还获得了两个相关图案：一个是具有受控 Pt 壳厚度的 Au-Pt 双金属纳米点的六方纳米图案，另一个是 Pt 微片和 Au 纳米阵列的交错图案。因此，我们提出了一个在固体表面上生成一个或多个金属的规则微纳图案的平台。
