Electrochromic properties of pure and doped Nb2O5 coatings and devices

Abstract

Coatings of pure and Zr, Sn, Li, Ti and Mo doped niobium pentoxide have been prepared by the sol—gel process and deposited on ITO-coated glass using the dip coating technique. Their structure, morphology and electrochromic (EC) properties have been studied. The coatings are transparent and, depending on the nature and amount of the doping and the sintering temperature, they present a brown, gray or blue color after Li insertion. The EC properties of 4
