Synthesis of alloyed Zn1-:XMnxS nanowires with completely controlled compositions and tunable bandgaps

Abstract

This study reported the successful synthesis of Zn1-xMnxS nanowires with completely controlled compositions (0 ≤ x ≤ 1); the x values could be well controlled by tuning the feeding ratio of [(C4H9)2NCS2]2Zn to [(C4H9)2NCS2]2Mn precursors. The bandgaps of Zn1-xMnxS nanowires showed nonlinear bowing character versus the composition. This result provided an effective route for designing Mn-based ternary chalcogenide nanowires with specific bandgaps, which is significant for their better application in photonics and spintronics.
