Abstract

original image

Natural help: PbE nanotubes (E=S, Se, Te; see picture) have been synthesized by a novel biomolecule-assisted method at room temperature. The precursor nanowires self-assembled from nanocrystals synthesized in the presence of cysteine play crucial roles as both the lead source and template in the formation of the nanotubes, which exhibit an obvious quantum confinement effect.
