具有规定结构和性质的表面图案对于各种应用是高度期望的。经常需要增加表面图案的异质性。这项工作开辟了一条新的途径，通过结合两种通常单独应用的方式（即，支架和掩蔽）的单层胶体晶体（MCC）模板。高度有序，松散堆积的二元和三元表面图案实现了由一个单一的步骤热处理的金薄膜涂层MCC和非紧密堆积的MCC模板。我们的方法可以控制这些纳米级的二元和三元表面图案，如颗粒的大小，形状和组成，以及颗粒间的间距的参数。该技术使得能够制备良好定义的二元和三元表面图案，以实现定制的等离子体特性。此外，由于其易于编程和良好的可扩展性，这里提出的二元和三元表面图案可能在纳米光子学和生物医学中有价值的应用。具体实例包括经由表面增强拉曼散射的生物感测、等离子体增强太阳能电池的制造和水裂解。
Surface patterns with prescribed structures and properties are highly desirable for a variety of applications. Increasing the heterogeneity of surface patterns is frequently required. This work opens a new avenue toward creating nanoparticle arrays with multiple periodicities by combining two generally separately applied modalities (i.e., scaffolding and masking) of a monolayer colloidal crystal (MCC) template. Highly ordered, loosely packed binary and ternary surface patterns are realized by a single-step thermal treatment of a gold thin-film-coated MCC and a nonclose-packed MCC template. Our approach enables control of the parameters defining these nanoscale binary and ternary surface patterns, such as particle size, shape, and composition, as well as the interparticle spacing. This technique enables preparation of well-defined binary and ternary surface patterns to achieve customized plasmonic properties. Moreover, with their easy programmability and excellent scalability, the binary and ternary surface patterns presented here could have valuable applications in nanophotonics and biomedicine. Specific examples include biosensing via surface-enhanced Raman scattering, fabrication of plasmonic-enhanced solar cells, and water splitting.
