Abstract:

We report herein a simple colloidal synthesis route, i.e., rapid injection of E (E = S, Se) source into a hot solvent (1-octadecence, ODE) containing antimony precursor (antimony stearate), to grow Sb₂E₃ nanorods. The as-prepared nanorods were extensively characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and high-resolution transmission electron microscopy (HRTEM). The mechanism for growth of Sb₂E₃ nanorods was also clarified from the view of crystal structure-directed growth. We believe that the method present here is a more straightforward and costeffective route to prepare Sb₂E₃ nanocrystals with high quality.
