Synthesis and characterization of Zn3P2/ZnS core/shell nanowires

► Fully-surrounded Zn3P2/ZnS core/shell NWs were synthesized via a two-step method. ► The structure of core/shell can be controlled. ► The core/shell NW growth method used can be extended to other material system. ► The band structure analysis shows the core-shell NWs have type-II heterostructure.
