Abstract
Self-ordered nanoporous nickel oxide/fluoride composite layers were grown by anodization of a Ni substrate in 85% H3PO4 solution containing 0.5 M NH4F. This oxide film contained a very high concentration of NiF2 (up to 30-40%). The layers show a very good electrochromic performance. In fact, the nanoporous oxide/fluoride films exhibit a nearly twofold stronger optical contrast and much higher cycling stability than the fluoride-free reference Ni oxide films.
