... contain defects with hexagonal and pentagonal cross sections. The hexagonal phases of WO3 is at the basis of its electrochromic behaviour. In fact, the “empty area” between the WO6 octahedra is so large ...
TiO2
Titanium dioxide (TiO2) is another cathodic electrochromic material. It has different crystal structures: rutile, anatase and brookite. Another structure, indicated as TiO2 (II), has been seen ...
The electrochromism was first discovered in WO3 in 1969 by Deb and since that time a huge number of papers have been published regards tungsten trioxide thin film.
