Bismuth Sulfide Properties
About Bismuth Sulfide Bi2S3 Powder:
Bismuth sulfide chemical formula is Bi2S3. It is also called bismuth trisulfideBismuth sulfide molecular weight is 514.15. Brown-yellow powder or crystal. Specific gravity is 7.39. Decomposes at 685℃. Insoluble in water and ethyl acetate, but soluble in nitric acid and hydrochloric acid. Bismuth sulphide is made by melting metallic bismuth with sulfur or passing hydrogen sulfide into bismuth salt solution. Used to prepare 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. Because the properties of nano-materials depend to a large extent on the morphology of nanomaterials, it is of substantial significance to synthesize more bismuth-sulfide nanostructures with special morphologies.
Bismuth sulfide Bi2S3, as an important semiconductor material, has potential application value in thermoelectric, electronic and optoelectronic devices and infrared spectroscopy. The bandgap energy of bismuth sulfide at room temperature is 1.33eV, which can be used to make photoelectric converters and is widely used in thermoelectric cooling processes. Nano-scale bismuth sulfide can not only blue-shift the ultraviolet-visible absorption wavelength and fluorescence emission wavelength, but also generate a nonlinear optical response, enhance the redox ability of nanoparticles, and has the excellent photoelectric catalytic performance. It has broad application prospects in luminescent materials, nonlinear optical materials and photocatalytic materials.

How is Bismuth Sulfide Bi2S3 Powder produced?
Bismuth sulfide is made by melting metallic bismuth with sulfur or transferring hydrogen sulfide into a bismuth salt solution. Used to make bismuth compounds, used to make other bismuth compounds.

Applications of Bismuth Sulfide Bi2S3 Powder:
Bismuth sulfide powder can be used for the preparation of bismuth sulfide nanoplates nano-platelets and ultrathinthin films.
Bismuth sulfide powder is suitable for liquid chemical peeling to prepare Bi2S3 nanosheets and nanoparticles, up to several layers of thin films. 10% deionized water in 90% isopropanol is the best mixed solvent for efficient peeling of layered Bi2S3 nanosheets.
Bismuth sulfide (Bi2S3) has a favorable bandgap of 1.3 eV (close to infrared light) and a relatively large absorption coefficient. It can be used in solution-processed thermoelectric devices, photodetectors, photosensitizers, solar cells and supercapacitors. Bi2S3 is also an interesting candidate for polymer-nanoparticle solar cells.
Bismuth sulfide has the advantages of environmental friendliness, photoconductivity, and nonlinear optical response. It is widely used in solar cells, photodiode arrays, and infrared spectroscopy. It can also be used to make other bismuth compounds, free-cutting steel additives, the Microelectronics industry.

Storage Condition of Bismuth Sulfide Bi2S3 Powder:
Damp reunion will affect Bi2S3 powder dispersion performance and using effects, therefore, Bismuth Sulfide Bi2S3 Powder should be sealed in vacuum packing and stored in the cool and dry room, the Bismuth Sulfide Bi2S3 Powder can not be exposure to air.
