| Abstract: | Tube-like SbzSe3 was synthesized by solid-state sintering method, and it was characterized by Scanning Electron Microscope （SEM）, X-ray power diffraction （XRD）, transmission electron microscope （TEM）, Raman Spectra and Differential Scanning Calorimeter （DSC）. The results indicate that Sb2Se3 micro tubes is orthorhombic phase and the lattice constants are a （11.6445A）, b （11.792A）, and c （3.981 A）. The TEM shows that the SbzSe3 micro-tube is crystalline and grows along 001] prientation. The melting point of SbzSe3 is 624.5℃ tested by DSC method. At the same time, the polycrystalline Sb-Se material with different ration is manufactured by sintering solid-state sintering method, and the structure is tested by XRD and Raman Spectra. |
