Why Bismuth Sulfide is an Important Semiconductor Material

What is Bi2S3 Powder?
Bi2S3 Powder is a direct band gap semiconductor material with many excellent properties. Bismuth sulfide belongs to the orthorhombic crystal system, and its energy bandwidth is 1.2~1.7eV. It can not only make the fluorescence emission and absorption wavelength blue shift but also enhance the redox energy of nanoparticles. It has relatively good photocatalytic performance and has potential application value in thermoelectric, electronic and optoelectronic devices and light-emitting materials. Two factors determine the preferred growth direction of Bi2S3 crystal: its layered structure and high anisotropy. The morphology of bismuth sulfide prepared includes spherical, rod, tubular, linear, flower and sheet micro nanostructures.

Preparation of Bi2S3 micro nano
The standard methods for preparing Bi2S3 micro/nanostructures include the sol-gel template method, solvothermal method, hydrothermal method, reflux method, microwave method, surfactant-assisted hydrothermal treatment method, etc. So far, researchers have made some progress in exploring Bi2S3, and new processes are constantly emerging to prepare Bi2S3 nanomaterials and apply them. There has been a lot of work on preparing Bi2S3 nanostructures with different morphologies. However, there are relatively few reports on the preparation of bismuth sulfide composite structures, and there are still some external factors to overcome when bismuth sulfide is compounded with other materials; In addition, it is not systematic to control a single variable to study Bi2S3 nanomaterials, such as the influence of reaction materials, reaction time and different substrates on their morphology. It still needs to be mature to realize controllable synthesis at low cost and low temperature under other conditions, which requires systematic research and summary. Therefore, we optimized different conditions to prepare micro nanomaterials of bismuth sulfide and its composites with uniform morphology and size.
Application of Bi2S3 Powder
Bi2S3 Powder, as an important semiconductor material, 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 widely used in thermoelectric cooling process Bismuth sulfide at nanometer level can not only make the absorption wavelength of ultraviolet visible Chemicalbook and fluorescence emission wavelength blue shift, but also produce nonlinear optical response, enhance the redox ability of nanoparticles. At the same time, it also has excellent photoelectric catalytic performance, and has broad application prospects in luminescent materials, nonlinear optical materials, photocatalytic materials, etc. Solubility in water (g/100ml)
Harm of Bi2S3 Powder to human body
Symptoms of chronic bismuth poisoning include anorexia, weakness, rheumatism, dysentery, fever, gingival metal thread, gingivitis, and dermatitis. Jaundice and conjunctival congestion are occasionally seen. Bismuth nephropathy may occur with proteinuria. The kidney has the highest concentration, and the liver is low. Bismuth can also reach the fetus through the amniotic membrane: causing a lousy heart, headache, and vomiting. To our knowledge, these chemicals' physical and toxic properties have not been thoroughly studied.
Price of Bi2S3 Powder
Bi2S3 Powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Bi2S3 Powder. A large amount of large amount will be lower. The Price of Bi2S3 Powder can be found on our company's official website.
