Structural color fabrication attracting significant interest for science and art is usually restricted by costly and time-consuming structuring processes or inerasable characteristics of structures. Herein, by developing a universal, low-cost technical solution—the nanosecond laser irradiation of ink (Solvent Black 7) layers coated on metal—laser-induced heterogeneous permanent/erasable nanostructures (LIHPEN) are produced successfully on multiple metals, especially noble metals, without ablation damage to intrinsic surfaces. LIHPEN consist of uniform laser-induced periodic surface structures produced by surface plasmon polariton excitation of metals and can be extended into 2D hybrid micro/nanostructures by introducing the direct laser interference patterning technique. LIHPEN technology operated under a large processing parameter window can realize space-selective erasability of prepared structures by controlling processing parameters, which determine the ink-layer carbonization degree and thus the permanent or erasable characteristic. Because ink layers can be coated manually, in addition to realizing digital scanning patterns, LIHPEN technology can be integrated with traditional artistic techniques to solidify and color artworks without risk of information loss and leakage in digital copying. LIHPEN with good durability can exhibit vivid structural colors on metals, demonstrating its great potential in fields of artwork iridescent coloring, encryption, and anti-counterfeiting, particularly those requiring customization, personalization, and rewritability.

金属上墨水辅助激光诱导异质永久/可擦除纳米结构
引起科学和艺术极大兴趣的结构色彩制造通常受到昂贵且耗时的结构化过程或结构的不可擦除特征的限制。在此,通过开发一种通用的、低成本的技术解决方案——纳秒激光照射涂在金属上的油墨(溶剂黑7)层——激光诱导异质永久/可擦除纳米结构(LIHPEN)在多种金属,特别是贵金属上成功生产,不会对内部表面造成烧蚀损坏。LIHPEN 由金属表面等离子体激元激发产生的均匀激光诱导周期性表面结构组成,并且可以通过引入直接激光干涉图案化技术扩展到二维混合微/纳米结构。LIHPEN技术在大加工参数窗口下运行,可以通过控制加工参数来实现所制备结构的空间选择性可擦除性,这些参数决定了墨层碳化程度,从而决定了永久或可擦除特性。由于可以手动涂覆墨层,除了实现数字扫描图案外,LIHPEN技术还可以与传统艺术技术相结合,对艺术品进行固化和着色,而不会出现数字复印中信息丢失和泄漏的风险。LIHPEN具有良好的耐用性,可以在金属上呈现出鲜艳的结构色彩,在艺术品虹彩着色、加密和防伪领域,特别是那些需要定制、个性化和可重写性的领域展现出巨大的潜力。
