Fabrication of High Aspect Ratio Core−Shell CdS−Mn/ZnS Nanowires by a Two Step Solvothermal Process

High Resolution Image Download MS PowerPoint Slide Synthesis of thin (5−8 nm) CdS−Mn/ZnS core−shell nanowires (CSNWs) with high aspect ratio (up 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.
