What is the structure of bismuth sulfide?

What is Bismuth sulfide powder?
The chemical formula of bismuth sulfide is Bi2S3. Molecular weight 514.15. Brown powder or crystal. Specific gravity is 7.39. Decomposition at 685. Insoluble in water and ethyl acetate, soluble in nitric acid and hydrochloric acid. It is prepared by melting metal bismuth and sulfur together or introducing hydrogen sulfide into a bismuth salt solution. A compound used to prepare bismuth. Bismuth sulfide is an important semiconductor material, and its application in photoelectric elements, thermoelectric equipment, and so on brings great convenience to human beings. Nano-bismuth sulfide makes its various properties more optimized because the performance of nano-materials depends largely on the morphology of nano-materials, so it is of substantial significance to synthesize more bismuth sulfide nanostructures with special morphology.
structure of Bismuth sulfide powder
Bi2S3 has a special layered structure and weak bonds between layered units, which leads to the anisotropy of Bi2S3 growth and the crystal nucleus growing into tiny flaky crystals in solvothermal synthesis and hydrothermal synthesis. At relatively low temperatures, the crystal growth rate of reactants is faster than the nucleation rate, which is beneficial to the growth of Bi2S3 into nano-flakes in solvents with high viscosity and high surface tension. The powder synthesized in distilled water and distilled water-ethylene glycol (2: 1) with high viscosity and high surface tension is beneficial to the formation of nano-flake structure. However, the surface tension energy and viscosity between Bi2S3 and 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 rate of Bi2S3 crystal is the fastest along the direction of the strongest bond chain, which eventually leads to the formation of Bi2S3 nanorods. To sum up, it can be inferred that the surface tension energy between Bi2S3 and solvent distilled water and distilled water-ethylene glycol is higher than that between Bi2S3 and solvent DMF. Solvents with high surface tension and high viscosity are beneficial to the formation of nano-flakes, while solvents with low viscosity and low surface tension are beneficial to the formation of rod-like structures.
