Synthesis and characterization of ternary chalcogenide ZnCdS 1D nanostructures

Abstract

1D nanostructures of ternary chalcogenide, ZnCdS–Cd nanocables and ZnCdS nanotubes, have been synthesized through a thermochemical process. The as-prepared nanocables consist of a single-crystal Cd core with a mean diameter of 90 nm and a single-crystal ZnCdS sheath with a thickness of 8 nm. The Cd core and the ZnCdS sheath are coaxially arranged. The as-prepared nanotube has the same structure as the sheath of ZnCdS–Cd nanocables with a hexagonal Zn 0.78Cd 0.22S phase. The formation of ZnCdS nanotubes results from the evaporation of the Cd core. The cathodoluminescence spectrum of ZnCdS–Cd nanocables displays an emission peak at 490 nm, and the emission peak is just between those of ZnS and CdS.
