Structural colors resulting from nanostructured metallic surfaces hold a series of advantages compared to conventional chemical pigments and dyes, such as enhanced durability, tunability, scalability, and low consumption, making them particularly promising for preparing color-tunable devices. However, once these structures are fabricated, they are almost all passive devices with static nanostructures and fixed optical properties, limiting their potential applications. Here, by using a specially designed array of ordered SiO₂ nanoholes as a deposition template in conjunction with the traditional reversible metal electrodeposition device (RMED), we propose a tunable reflective surface where the color of the surface can be changed as a function of the thickness of the deposited Ag nanoparticles (AgNPs). Simplified manufacturability and a large range of color tunability are achieved over previous reports by utilizing the SiO₂ nanohole template, which allows the direct deposition of AgNPs while forming an array structure of Ag nanocylinders. Besides, a further thematic analysis of the physical mechanism in the proposed structure is conducted. The results show that the structural colors induced by the longitudinal localized surface plasmon resonance (LSPR) mode can be dynamically tuned from brown to purple via increasing the deposition thickness. Additionally, in combination with SiO₂ nanohole templates of varying parameters, a full gamut of colors spanning the entire visible spectrum is achieved, revealing the feasibility of utilizing the properties of the LSPR mode for satisfying various color requirements. We believe that this LSPR-based multicolor RMED design will contribute to the development of full color information displays and light-modulating devices.

与传统的化学颜料和染料相比，由纳米结构金属表面产生的结构颜色具有一系列优势，例如增强的耐用性、可调性、可扩展性和低消耗，使其特别有希望用于制备颜色可调器件。然而，一旦这些结构被制造出来，它们几乎都是具有静态纳米结构和固定光学特性的无源器件，限制了它们的潜在应用。在这里，通过使用专门设计的有序 SiO _2阵列纳米孔作为沉积模板与传统的可逆金属电沉积装置 (RMED) 相结合，我们提出了一种可调反射表面，其中表面的颜色可以根据沉积的 Ag 纳米颗粒 (AgNPs) 的厚度而改变。与以前的报告相比，通过利用 SiO _{2实现了简化的可制造性和大范围的颜色可调性}纳米孔模板，允许直接沉积 AgNPs，同时形成 Ag 纳米圆柱的阵列结构。此外，对所提出结构中的物理机制进行了进一步的专题分析。结果表明，纵向局域表面等离子体共振（LSPR）模式诱导的结构颜色可以通过增加沉积厚度从棕色动态调整到紫色。此外，与 SiO _2结合不同参数的纳米孔模板，实现了跨越整个可见光谱的全色域，揭示了利用 LSPR 模式的特性来满足各种颜色要求的可行性。我们相信这种基于 LSPR 的多色 RMED 设计将有助于全彩信息显示器和调光设备的发展。
