Overview of bismuth sulfide

Bismuth sulfide, chemical formula Bi2S3. Molecular weight 514.15. Brown-yellow powder or crystal. Specific gravity 7.39. Decomposes at 685℃. It is insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid. It is made of metallic bismuth and sulfur or it is made by transferring hydrogen sulfide to a bismuth salt solution. 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 performance of nanomaterials depends to a large extent on the morphology of nanomaterials, it is of great significance to synthesize more bismuth sulfide nanostructures with special morphologies.

Uses of bismuth sulfide:

Bismuth sulfide has the advantages of environment, 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 the microelectronics industry. Bismuth sulfide powder can be used to prepare bismuth sulfide nanosheets, nanosheets and ultra-thin films.

Bismuth sulfide powder is suitable for liquid chemical stripping to prepare Bi2S3 nanosheets and nanoparticles, and can form multiple films at most.

Bismuth sulfide (Bi2S3) has a good band gap of 1.3 eV (close to infrared light) and a large absorption coefficient. It can be used in solution processing thermoelectric devices, photodetectors, photosensitizers, solar cells and super capacitors. Bi2S3 is also an interesting candidate material for polymer nanoparticle solar cells.
