The key features of Bismuth Sulfide powder
Bi2S3’s unique layered structure, and weak bonds among layered units, leads to anisotropies in Bi2S3’s growth. These conditions also allow for the growth nuclei into small flake-like crystals through solvothermal and/or hydrothermal synthesis. At relatively low temperatures, crystal growth rates of reactants are faster than nucleation rates, which favors growth of bi2S3 nanoflakes in solvents that have high viscosity or high surface tension. Powders made in high viscosity, high surface tension solvents distilled and distilled-ethylene glycol (2 to 1) favored the formation nanoflake structures. Bi2S3 and solvents DMF have relatively low surface tension energy, viscosity, and viscosity. This is advantageous for strengthening the chemical force between SBi bonds in the chains. According to the PBC theory, crystal growth of Bi2S3 crystals occurs along the maximum force. Bi2S3 nanorods are formed in the direction of strong bond chains, which has the fastest growth rate.

Bismuth Sulfide, an important semiconductor material has potential applications as a thermoelectric, electronic, and optoelectronic device and infrared. Bismuth sulfide’s band gap energy at room temperature is 1.33eV. This is useful for making photoelectric converters, and it is used extensively in thermoelectric cooling processes. Nano-scale bismuth-sulfide can blue-shift the wavelengths for ultraviolet-visible absorption, fluorescence emission wavelength, and also produce the nonlinear optical response, which enhances nanoparticles’ redox abilities and provides excellent photoelectric catalyst performance. There are many potential applications of it in luminescent materials and nonlinear optic materials.
