Photoinduced electrochromic effect and its applications to displays
Abstract
A liquid solution of an organic donor of the pyrazoline class in a halogenated solvent placed between two transparent electrodes shows blue-color-generating electrochromism whose coloring intensity can be controlled by external illumination. The effect seems to be applicable to optically addressable direct-view passive displays.
