摘要：
Synthesis of thin (5-8 nm) CdS-Mn/ZnS core-shell nanowires (CSNWs) with high aspect ratio (up to similar to 150) is reported for the first time. The modified solvothermal synthesis of CSNW involved two steps: the formation of Mn-doped CdS core followed by the ZnS shell. The CSNW growth process is engineered in such a way that the ZnS shell layer grew radially onto the prematurely grown CdS-Mn core, that is, prior to the formation of its well-faceted surface.
