我们介绍了第一个等离子体调色板利用颜色生成策略与铝纳米结构的逼真印刷。我们的工作通过空间混合和调整离散纳米结构的纳米级间距来扩展可见色彩空间。与常用的等离子体材料（如金和银）相比，铝作为等离子体材料，我们的纳米结构实现了增强的耐用性和显著降低的材料成本，以及可扩展到更高通量方法（如光刻和纳米压印光刻）的尺寸体系。这些进步可以为新一代低成本、高分辨率、等离子体彩色打印铺平道路，并直接应用于安全标签、密码学和信息存储。
We introduce the first plasmonic palette utilizing color generation strategies for photorealistic printing with aluminum nanostructures. Our work expands the visible color space through spatially mixing and adjusting the nanoscale spacing of discrete nanostructures. With aluminum as the plasmonic material, we achieved enhanced durability and dramatically reduced materials costs with our nanostructures compared to commonly used plasmonic materials such as gold and silver, as well as size regimes scalable to higher-throughput approaches such as photolithography and nano-imprint lithography. These advances could pave the way toward a new generation of low-cost, high-resolution, plasmonic color printing with direct applications in security tagging, cryptography, and information storage.
