Abstract
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.
