We have successfully grown the tin oxide (SnO 2 ) fishbone‐like nanostructures on titanium nitride (TiN)‐coated substrates by the thermal evaporation of Sn powders. X‐ray diffraction indicated that the product had the phase structure of the rutile form of SnO 2 . Transmission electron microscopy (TEM) revealed that the product consisted of fishbone‐like structure, with branches and sub‐branches attached to the main stem. High‐resolution TEM and selected area diffraction pattern coincidentally indicated that both branches and sub‐branches were single crystalline rutile SnO 2 structures. Room temperature photoluminescnece (PL) spectrum of the as‐synthesized SnO 2 nanostructures exhibited peaks associated with the visible light emission. (© 2005 WILEY‐VCH Verlag GmbH & Co.
