Surfactant-assisted solvothermal synthesis of Bi_2S_3 nanorods

摘要

Bi_2S_3 nanorods have been synthesized by the surfactant-assisting solvothermal method. When different conditions were chosen, the high-quality one-dimensional (1D) products were obtained in n-butanol-water solvent, and thioacetamide decomposition provided S~(2-) for forming the single-crystalline structure of the sulfide at 120 ℃. They were characterized by HRTEM, powder X-ray diffraction and PL measurements. Their formation mechanism was also proposed.
