Mn-doped ZnS nanobelts have been prepared through a thermal evaporation method at 1100 °C.The synthesized nanobelts are characterized with X-ray diffraction(XRD),scanning electron microscopy(SEM),selected area electron diffraction(SAED),high-resolution transmission electron microscopy(HRTEM),and photoluminescence(PL) spectroscopy.The results show that the nanobelts have an uniform single-crystal hexagonal wurtzite structure and grow along [0001] direction.Room-temperature photoluminescence reveals that the intrinsic PL of the nanobelts disappears and a new PL peak of the Mn-doped ZnS nanobelts emerges at 575 nm.
