Direct Synthesis of Se@CdSe Nanocables and CdSe Nanotubes by Reacting Cadmium Salts with Se Nanowires

Se@CdSe nanocables and CdSe nanotubes with diameters of around 50 nm (see Figure) can be directly synthesized via a template‐ engaged approach in aqueous solution. The walls of these nanotubes are composed of CdSe nanoparticles 5–10 nm in size. It is believed this approach can be potentially extended to process many other chalcogenides into tubular nanostructures.
