Fabrication and Optical Properties of Mn Doped ZnS Nanowires
Mn doped ZnS nanowires with typical wurtzite single-crystalline structure were successfully synthesized via H2 assistant chemical evaporation deposition method. The investigations indicated that the diameter of Mn/ZnS Nanowire with high aspect ratio is 25~40nm, EDS results show that the content of Mn element is about 4.45at%. HRTEM and SAED results demonstrated that the Mn/ZnS nanowires grow along  direction, which was different from the common direction reported in literatures. Room temperature photoluminescence properties were also examined, showing a strong green emission centered at 523.04 nm, and a weak emission at 382.53 nm was also observed, showing a red shift of 45.53 nm comparing to the intrinsic luminescence.
