A complete composition tunability of ternary Zn.Cdc.S alloyed nanowires on a single substrate has been achieved by vapor-liquid-solid (VLS) growth. The compositions of the as-grown nanowires along the substrate can be modulated from pure ZnS to pure CdS by simply controlling the local temperature. Photoluminescence spectra showed that the band edge emissions of these alloyed nanowires with the peak wavelength can be gradually tuned from green (508 nm) at the CdS-rich end to near UV (360 nm) at the ZnS-rich end.
