Fabrication of ZnS ∕ SiC nanocables, SiC -shelled ZnS nanoribbons(and sheets), and SiC nanotubes (and tubes)

Here we report on the synthesis of ZnS ∕ SiC nanocables and SiC nanotubes and other relevant structures via a controllable two-stage thermal process using ZnS nanowires, nanoribbons, and sheets as templates. Within the cables, the ZnS cores are polytypes of fcc- and hcp- ZnS with ∼ 50 - 130 nm diameter, and the SiC shells are polycrystalline β - SiC with ∼ 15 - 50 nm thickness. SiC nanotubes were formed through simple removal of ZnS cores from the cables. Room-temperature photoluminescence of the SiC nanotubes displays a strong green emission band centered at ∼ 517 nm . The nanostructures described herewith may be valuable in the blocks of advanced semiconducting devices.
