A new interesting growth phenomenon for amorphous materials has been discovered for silica fibers prepared by a Sn‐assisted vapor–liquid–solid growth method. The fibers exhibit triangular cross sections (see figure) and are surface decorated with SnO 2 nanoparticles, forming SiO 2 /SnO 2 heterostructures. They have a typical length of several tens of micrometers (some may even reach a length of over 100 μm) and a mean diameter of ca. 0.5–2.5 μm.
