Two flame‐based synthesis methods are presented for fabricating ZnO‐nanostructure‐based UV photodetectors: burner flame transport synthesis (B‐FTS)and crucible flame transport synthesis (C‐FTS). B‐FTS allows rapid growth of ZnO nanotetrapods and in situ bridging of them into electrical contacts. The photo detector made from interconnected ZnO nanotetrapod networks exhibits fast response/recovery times and a high current ratio under UV illumination.
