Lead Chalcogenide Nanotubes Synthesized by Biomolecule-Assisted Self-Assembly of Nanocrystals at Room Temperature

摘要

Since the discovery of carbon nanotubes in 1991,[1] extensive research has been carried out on one-dimensional nanostructures because of their unique properties.[2]-[6] Various methods have been developed for the synthesis of nanotubes.[7] In general, it is relatively easy for layered materials to form nanotubes directly under the appropriate experimental conditions.[8] For materials that do not have a layered structure, nanotubes may be synthesized by a variety of methods, such as decomposition of the precursor,[9] template-assisted growth,[8], [10]-[14] self-assembly,[15], [16] and vapor deposition.[17], [18] However, these methods are still limited to the synthesis of specific kinds of nanotubes.
