| Ternary tungsten oxide systems can be categorized by two groups: i) reduced, non-stoichiometric tungsten bronzes and ii) fully oxidized insulating phases [1, 2]. Bronzes form when WO3 is reduced, normally by exposure to the vapor of a guest or “impurity” metal. There are several possible resulting bronze structures involving either square [3], pentagonal [4], or hexagonal [5, 6] tunnels.
