Abstract
Single-crystalline Bi2S3 nanostructures have been synthesized by reacting BiCl3 with sodium thiosulfate via a simple solvothermal treatment. Various techniques such as X-ray diffraction (XRD), field-emission scanning electron microscope (FESEM), high-resolution transmission electron microscope (HRTEM), selected area electron diffraction (SAED), UV–visible spectrometry (UV–vis) and photoluminescence spectrometry (PL) have been used to characterize the obtained products. The results show that the products are orthorhombic-structured Bi2S3 nanocrystals. By reacting in different solvents, the shapes of Bi2S3 nanostructures are changed obviously. The solvent effects are discussed in detailed, and the interior growth mechanism is proposed.
