Selenide Compounds

Selenide Compounds mainly refer to the metal elements and metalloid compounds, which have stoichiometric composition changing within a certain range to form a compound-based solid solution. Inter-metallic compound is of its excellent properties between the metal and ceramic, and become an important branch of the new structural materials. Selenide compound of Antimony Selenide Sb₂Se₃, Arsenic Selenide As₂Se₃, Bismuth Selenide Bi₂Se₃, Cadmium Selenide CdSe, Copper Selenide CuSe, Gallium Selenide Ga₂Se₃, Indium Selenide In₂Se_3, Lead Selenide PbSe, Molybdenum Selenide MoSe₂, Tin Selenide SnSe, Tungsten Selenide WSe₂, Zinc Selenide ZnSe etc and its (Li, Na, K, Be, Mg, Ca) compounds and Rare Earth compounds can be synthesized in form of powder, granule, lump, bar and substrate.

Molybdenum Selenide

Molybdenum Selenide MoSe₂, gray solid crystalline appearance, layered structure, is an inorganic compound semiconductor of molybdenum and selenium, which is known as group VI transition metal dichalcofemides, CAS 12058-18-3, density 6.0g/cm³, MW 253.86, melting point 1200°C, insoluble in water. Bulk MoSe synthesis and purification involves direct reaction of molybdenum and selenium by chemical vapor transport CVT, singlr crytstal MoSe is produced by scotch tape exfoliation from bulk crystal or by chemical vapor deposition CVD. Molybdenum Selenide MoSe₂, narrow band gap of 1.2ev, can not only absorb ultraviolet light but also visible light, it exhibits a wide range of light response and high utilization efficiency of solar light, so it is used as photodetectors and transistors. Molybdenum Selenide’s layered nature and higher electrical conductivity gives rise to several interesting applications such as field effect transistors, piezoelectrics, and substrates for self assembly, and also for material modification, lubricant additives, solar cells, energy storage, microelectronics, optoelectronics and high performance photocatalysts. Molybdenum Selenide MoSe₂ at Western Minmetals (SC) Corporation with purity of 99.99% 4N can be delivered in form of submicro and nanomicron powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification.

Copper Selenide

Copper Selenide or Dicopper Selenide, Cuprous Selenide, Cu2Se CAS No 20405-64-5, black cubic crystal, density 6.749, melting point 1113°C, insoluble in water but easily soluble in nitric acid, soluble in sulfuric acid and ammonia. Copper Selenide is prepared in a vacuum quartz seal tube placed in horizontal synthesis furnace. Ligand-stabilized copper selenide (Cu(2-x)Se) nanocrystal is synthesized by a colloidal hot injection process, which readily disperse in water and exhibit strong near-infrared (NIR) optical absorption with a high molar extinction coefficient, it finds application in photothermal therapy, ad for the preparation of group compound semiconductor, cuprous selenide target material, copper-indium-gallium-Selenium CIGS thin film solar cell etc. Copper Selenide CuSe at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, pill, needle, blank, bulk crystal and single crystal etc or as customized specification.
