Single crystalline tungsten oxide nanowires (TONWs) have been synthesized on highly flexible, highly conductive, and highly robust carbon cloth by a catalyst‐free thermal evaporation method. Field emission with a low threshold field of ∼4.30 MV m −1 was observed from the TONWs. This finding opens up opportunities to make light weight and rollable field emission displays.
