Surfactant-assisted solvothermal synthesis of Bi2S3 nanorods

Bi2S3 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 S2− for forming the single-crystalline structure of the sulfide at 120 °C. They were characterized by HRTEM, powder X-ray diffraction and PL measurements. Their formation mechanism was also proposed.
