Abstract

Tungsten trioxide (WO3) nanoparticles are synthesized via a sol-gel route using metallic tungsten as precursor and printed on a flexible electrode using inkjet printing in order to build solid-state electrochromic cells. A method for separate control of different spectral regions of the electrochromic device (near infrared and visible) is disclosed.
