Very long and highly oriented potassium‐doped tungsten oxide nanowires (see Figure) can be synthesized using the simple technique presented here. The mechanism of nanowire formation is investigated and a vapor–liquid–solid mechanism is proposed. This novel method can be easily scaled up and can also be extended to the preparation of nanowire arrays of other materials.
