Overview of 99.99% CAS 1315-05-5 Sb2Se3 Powder Antimony Selenide
Telluride and selenide compounds play a significant role in the field of semiconductors, particularly in the development of advanced electronic and optoelectronic devices. These materials belong to the chalcogenide family, characterized by their ability to form compounds with elements from groups IV-VI in the periodic table.
Tellurides: Compounds containing tellurium (Te) as the chalcogen. Examples include cadmium telluride (CdTe), mercury telluride (HgTe), and zinc telluride (ZnTe). These materials have found applications in solar cells, infrared detectors, and high-speed electronics due to their tunable bandgap, high electron mobility, and good thermal stability.
Selenides: Similar to tellurides, but with selenium (Se) replacing tellurium. Notable examples are cadmium selenide (CdSe), gallium selenide (GaSe), and zinc selenide (ZnSe). Selenide compounds are widely used in light-emitting diodes (LEDs), laser diodes, and solar cells due to their direct bandgap properties and efficient light absorption/emission capabilities.
Feature of 99.99% CAS 1315-05-5 Sb2Se3 Powder Antimony Selenide
Direct Bandgap: Many telluride and selenide semiconductors have direct bandgaps, which facilitate efficient light emission and absorption processes. This makes them suitable for optoelectronic applications such as LEDs and lasers.
Tunable Bandgap: The bandgap of these materials can be adjusted by alloying or altering the composition (e.g., CdSe to CdTe), enabling customization for specific device requirements across a wide spectrum of wavelengths.
High Electron Mobility: Materials like HgCdTe exhibit high electron mobility, which is crucial for high-speed electronic devices and low-noise detector applications.
Thermal Stability: Some tellurides and selenides, like ZnTe and ZnSe, demonstrate good thermal stability, making them suitable for high-temperature operation and processing.
Non-Toxic Alternatives: With increasing environmental concerns, there’s a push towards exploring less toxic alternatives to commonly used semiconductors. For instance, Cd-based tellurides and selenides are being replaced or combined with less toxic elements like Mg or Mn in some applications.

Parameters of 99.99% CAS 1315-05-5 Sb2Se3 Powder Antimony Selenide
Antimony Selenide (Sb2Se3), also known as Stibnite, is a fascinating inorganic compound that falls under the chemical formula Sb2Se3. With a purity level of 99.99%, this high-quality powder form of the material ensures exceptional performance and reliability in various applications. The CAS number, 1315-05-5, serves as a unique identifier for this specific compound within the scientific community.
Sb2Se3 is an intrinsically semiconductor material, which means it exhibits properties that lie between conductors and insulators. It has gained significant attention due to its versatile nature and potential applications in optoelectronics, solar cells, and thin-film technologies. The compound’s structure consists of antimony (Sb) atoms forming a trigonal planar coordination with selenium (Se) atoms, creating a layered crystal lattice.
The powder form of Sb2Se3 offers several advantages. Firstly, the particle size is typically controlled during the manufacturing process, allowing for better dispersion and homogeneity when incorporated into other materials. This is crucial for achieving optimal performance in composite materials and thin films. The ultra-high purity of 99.99% ensures minimal contamination, which is essential for applications where impurities could compromise device functionality.
In photovoltaic devices, Sb2Se3 can be used as a light absorber or as a buffer layer, improving the efficiency of solar cells by facilitating charge separation and transport. Its tunable bandgap, ranging from indirect to direct depending on the synthesis conditions, makes it adaptable for different wavelength ranges. Moreover, its low cost and earth-abundance make it an attractive alternative to more expensive semiconductors.
Antimony selenide also finds applications in optoelectronics, where it is employed in light-emitting diodes (LEDs) and photodetectors. Its ability to emit light in the infrared region, combined with its sensitivity to photons, makes it suitable for sensing and communication technologies.
In the field of electronics, Sb2Se3 can be utilized as a component in thermoelectric generators, converting temperature differences into electrical energy. Its high Seebeck coefficient and relatively low thermal conductivity make it a promising material for waste heat recovery and power generation systems.
However, it’s important to note that despite its numerous benefits, Sb2Se3 is not without challenges. Environmental concerns regarding the disposal and toxicity of antimony have led to research into developing safer alternatives or recycling methods. Additionally, the synthesis process requires careful control to achieve the desired properties, and further optimization is often necessary for practical implementation.
In summary, Sb2Se3 with a purity of 99.99% and CAS number 1315-05-5 is a highly sought-after material due to its versatile semiconductor properties and potential applications in optoelectronics, solar energy, and thermoelectricity. While there are ongoing efforts to address its environmental impact, its current and future prospects make it a valuable material in modern technology.
