title: Photoinduced reversible changes in morphology of plasmonic Ag nanorods on TiO2 and application to versatile photochromism.
abstract: We achieved reversible changes in length and spectrum of Ag nanorods based on plasmon-induced photoelectrochemical reactions. The changes are applied to multi-wavelength and dual-polarization photochromism in visible-infrared regions. It allows display of invisible images viewable only by infrared cameras. Also possible is display of superimposed visible and invisible images.
