Bismuth sulfide overview
Bismuth sulfide, chemical formula Bi2S3. Molecular weight 514.15. Brown-yellow powder or crystal. Specific gravity 7.39. 685 ℃ decomposition. Insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid. Sulfur or it is made by transferring hydrogen sulfide into a solution of bismuth salts. For the preparation of bismuth compounds. Bismuth sulfide is an important semiconductor material, and its application in optoelectronic components and thermoelectric devices has brought great convenience to mankind. Nano-bismuth sulfide makes its various properties more optimized. Since the properties of nanomaterials largely depend on the morphology of nanomaterials, it is of great significance to synthesize more bismuth sulfide nanostructures with special morphologies.
Bismuth sulfide is a chemical substance with the molecular formula Bi₂S₃, insoluble in water, toxic, weakly radioactive, and harmless to the human body.

Applications of Bismuth Sulphide
Bismuth sulfide has the advantages of environmental, photoconductivity, and nonlinear optical response. It is widely used in solar cells, photodiode arrays and infrared spectroscopy. It can also be used in the manufacture of other bismuth compounds, free-cutting steel additives and in the microelectronics industry. Bismuth sulfide powder can be used to prepare bismuth sulfide nanosheets, nanosheets and ultrathin films.
Bismuth sulfide powder is suitable for liquid chemical exfoliation to prepare Bi2S3 nanosheets and nanoparticles, which can form multilayer films at most.
Bismuth sulfide (Bi2S3) has a good band gap of 1.3 eV (near infrared light) and a large absorption coefficient. It can be used for solution processing thermoelectric devices, photodetectors, photosensitizers, solar cells and supercapacitors. Bi2S3 is also an interesting polymer nanoparticle solar cell candidate.
