What is Bismuth Sulfide Powder?
Bismuth sulfide is brownish-yellow powder or crystal with a specific gravity of 7.39. It decomposes at 685°C. Insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid.
The main features of Bismuth Sulfide Powder
Bi2S3 has a special layered structure and weak bonds between layered units, which lead to the anisotropy of Bi2S3 growth and the growth of nuclei into tiny flake-like crystals in solvothermal and hydrothermal synthesis. Under relatively low temperature conditions, the crystal growth rate of the reactants is faster than the nucleation rate, which favors the growth of Bi2S3 nanoflakes in solvents with high viscosity and high surface tension. The powders synthesized in high viscosity and high surface tension solvents distilled water and distilled water-ethylene glycol (2:1) favored the formation of nanoflake structures. The surface tension energy and viscosity between Bi2S3 and solvent DMF are relatively low, which is beneficial to strengthen the chemical force between S-Bi bonds in the chain. According to the PBC theory of crystal growth, the growth of Bi2S3 crystals is along the maximum force. The direction of the strong bond chain has the fastest growth rate, which eventually leads to the formation of Bi2S3 nanorods.

The applications of Bismuth Sulfide Powder
As an important semiconductor material, bismuth sulfide has potential applications in thermoelectric, electronic and optoelectronic devices and infrared spectroscopy. The band gap 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 produce The nonlinear optical response enhances the redox ability of nanoparticles, and also has excellent photoelectric catalytic performance. It has a wide range of application prospects in luminescent materials, nonlinear optical materials, and photocatalytic materials.
