Multicolored Electrochromic Device from the Reversible Aggregation and Decentralization of Silver Nanoparticles

A new multicolor electrochromic (EC) device based on Ag nanoparticle aggregation and decentralization is demonstrated. Color states that can reversibly be changed from transparent to yellow, pink, purple-violet, and dark blue under a constant direct-current field are obtained. Moreover, these color states remain after removing the electric field. A novel EC cell with eight indium tin oxide electrodes is fabricated to enhance the repeatability and stability of the system.
