Abstract

Multi-color electrochromic (EC) device was fabricated on a patterned ITO glass. Organic electrochromic dyes were encapsulated within nano-sized porous TiO2 nanoparticles, and their relative electrochromic (EC) properties were determined using spectroelectrochemical method. Blue, green, and red colored organic dye doped TiO2 nanoparticles were coated on a patterned ITO substrate to afford multi-colored EC electrode, which was coated with a photo-curable polymer electrolyte and then covered with a bare ITO glass as a counter electrode. Upon photocuring of the electrolyte layer under UV light, an all-solid state multi-colored electrochromic device (ECD) was obtained. The resultant ECD showed reversible multi-color change within 8 sec and high optical contrast.
