Abstract
Plasmonic colors have gained significant interest for flat panel displays due to their broad color gamut and high subwavelength resolution. The reversible metal deposition, having tunable nanostructures, along with their localized surface plasmon resonance (LSPR), is considered as a promising strategy for dynamic color displays. Herein, a demonstration of the manipulation of plasmonic silver adatoms through reversible metal deposition is presented for dynamic light modulation. The voltage-activated reversible silver nanoparticles deposition enables a wide range of dynamic plasmonic color change of 100 nm, and also facilitates a size and shape control of the grown silver nanoparticles. The silver nanoparticles interact with visible light through LSPR, the size and shape of the particles affect their optical properties. Our findings provide a favorable and novel platform for low energy-consumption tunable photonic and nanoplasmonic devices, as well as provide a simple and reliable process for rapid, scalable, and green preparation of tunable plasmonic Ag nanoparticles.
