Silver Electrodeposition Based Multicolor Electrochromic Device toward Plasmonic Nanophotoelectronics

We reported silver electrodeposition-based electrochromic device (ECD) which exhibited reversible color change from transparent to chromatic color, black and silver-mirror in a single device. This coloration is based on the absorption by localized surface plasmon resonance (LSPR) enhanced by the silver nano deposit. In this paper, we review a relationship between optical properties, deposition process and morphology of silver nanoparticles toward plasmonic nanophotoelectronics as well as color reflective display.
