研究目的
To provide an up-to-date overview of various plasmonic color ?ltering approaches and highlight their uses in a broad palette of applications, including high-density data storage, information encryption, and plasmonic information processing.
研究成果
The review concludes that metallic nanostructures show great potential for creating colorful plasmonic elements, with advantages such as subdiffraction spatial resolution, nontoxic material components, ultracompact architectures, and long-term durability. It also highlights the extensive growth in the field of plasmonic structural coloring and the potential applications of dynamically tunable plasmonic colors in switchable displays, optical cryptography, camouflage, chemical and biological sensors, and high-density data storage systems.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, include the inherent optical loss in metals and the radiation loss of plasmonic structures, which inevitably broaden the resonant linewidth, thereby decreasing the efficiency and reducing color saturation.
