Polycrystalline compounds is synthesized by the High-Pressure Vertical Bridgman method or High-Pressure Vertical Zone Melting, or distillation and CVD synthesis, which is used for growing CdSe single crystal, CdSe evaporation material, namely for making photocell, rectifier, luminous paint, etc. Cadmium Selenide with wurtzite crystal structure is an important II-VI n-type semiconductor, and has a band gap of 1.74 eV. CdSe nanoparticle by several production methods of arrested precipitation in solution, synthesis in structured media, high temperature pyrolysis, sonochemical, and radiolytic methods is of 1–100 nm in size, exhibits a property known as quantum confinement, they are finding applications in opto-electronic devices such as laser diodes that cover a large part of the electromagnetic spectrum,  especially useful as a component of photocatalysts, use in biomedical imaging applications, and is used in windows for instruments using infra-red (IR) light, nanosensing and high-efficiency solar cells. Cadmium Selenide CdSe at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N and  99.9999% 6N can be delivered in form of powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification. 

Lead Selenide

Lead Selenide PbSe, gray or grayish black crystalline solid, a selenide of lead, cubic crystal of the NaCl structure, CAS 12069-00-0, MW 286.16,density 8.10g/cm³, melting 1078°C, is  insoluble in water but soluble in nitric acid and hot concentrated hydrochloric acid. Lead Selenide is prepared by mixing high-purity lead and selenium in stoichiometric proportion and heating them in quartz ampoules to 1100-1150° in furnace or reduction of lead selenite with hydrogen. Lead selenide is a semiconductor material of direct bandgap of 0.27 eV at room temperature, which performs efficiently at low temperatures without the need for cooling. As a sensitive material to the infrared radiation, PbSe has unique and outstanding characteristics making this material an excellent detector of low cost high speed infrared imagers for thermal imaging operating at wavelengths between 1.5–5.2μm, and to make photosensitive resistance. Lead selenide nanocrystal can be used as quantum dots, for example in nanocrystal solar cells. Meanwhile, Lead Selenide is a high performance thermoelectric material which has a number of industrial applications. Lead Selenide PbSe at Western Minmetals (SC) Corporation with purity of 99.99% 4N can be delivered in form of powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification.

Tin Selenide

Tin Selenide SnSe, gray solid crystal with rhombic crystal structure, molecular weight 199.68, density 6.18g/cm³, melting point 861°C, can be dissolved in alkali metal sulfide and selenide, and easily soluble in nitric acid and aqua regia but insoluble in water. SnSe compound is typical layered material synthesized by the various methods employed for the phase-pure SnSe like hot injection, facile surfactant-free synthesis, thermal evaporation, insert gas condensation etc. Tin Selenide is an important IV-VI semiconductor, the indirect band gap of bulk materials is 0.90 EV and the direct band gap is 1.30 eV, which can absorb most of the solar spectrum, and been extensively explored in the thermoelectric fields and photovoltaic PV application for its extraordinary advantages including excellent optoelectronic properties, absence of toxicity, economically raw material, relative abundance, environmental friendliness and chemical stability. As tin-based binary chalcogenide compound, the electronic, thermoelectric, and optoelectronic characteristics of bulk crystals, thin films, and nanostructures of Tin Selenide SnSe finds novel applications in the next generation electronic, optical, optoelectronic, flexible systems, Li-ion rechargeable batteries, super capacitors, phase-change memory devices and topological insulators.
