摘要：

A solvothermal route was employed for the syntheses of nanocrystalline Sb2Se3 from the single source precursor Sb[Se2P((OPr)-Pr-i)(2)](3) at different temperatures. The products were shown to be nanowires by electron microscopy, and the composition was confirmed as Sb2Se3 by powder X-ray diffraction and energy dispersive spectroscopy. The diameter and length of the nanowires were extended at 150 degrees C, as compared to 100 degrees C in the solvothermal process. The direct band gap energy of the nanowires was estimated by absorption spectroscopy to be 1.49 eV. Structural elucidation of the precursor Sb[Se2P((OPr)-Pr-i)(2)](3) was completed by single crystal X-ray diffraction.
