Bismuth Sulfide Bi2S3 Powder CAS 1345-07-9

About Bismuth Sulfide Bi2S3 Powder:
Bismuth sulfide, Chemical formula Bi2S3. The 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. It 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.
