Abstract
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.
