| Outline of Final Research Achievements |
Electrochromic (EC) device is expected to be a potential candidate for novel reflective display and energy conservation system. We have demonstrated world's first Ag-electrodeposition based multi-color EC device by focusing on the result that Ag nanoparticles exhibit various optical states based on their localized surface plasmon resonance (LSPR). In this research, we achieved the memory property for two hours, which was the image retention properties without power supply and was essentially required for tone representation. Further, representation of the color with high lightness value (L value) was successfully demonstrated with the EC cell by optimizing the electrolyte component. It was revealed that the relation between the optical state and Ag particle structure was theoretically explained by FDTD modeling analysis. Consequently, we first realized the Ag LSPR based EC device which showed black, mirror, CMY and RGB and indicated the possibility to enable wide color gamut.
