    • Fabrication of crystalline Sb$_2$S$_3$ sheaf structure composed of nanorods by a hot-injection method


      More Details Abstract Fulltext PDF

      Herein,we demonstrate a hot-injection method towards the fabrication of Sb$_2$S$_3$. The evolution from amorphous Sb$_2$S$_3$ nanoparticles to a sheaf of Sb$_2$S$_3$ nanorods cross-linked together occurring with the increase of reaction temperature and time is studied. The structural, compositional and morphological features of Sb$_2$S$_3$ products indicate the formation of crystalline Sb$_2$S$_3$ with orthorhombic phase and high purity. As the reaction proceeds, it can be observed that the individual nanorod grows along the elongated direction ($c$-axis), and it is noteworthy that its round cross-section could develop into the rectangular cross-section subsequently. In this study we also propose a possible formation mechanism for the growthprocess of Sb$_2$S$_3$, and it reveals that the present hot-injection could provide an ideal growth environment for synthesizing the nanostructured materials by optimizing the experimental parameters.
