Cadmium Telluride (CdTe) is a crystal grown product generally immediately available in most volumes. technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Cadmium Telluride (CdTe) is also available as Quantum Dots. CdTe Quantum Dots have the widest wavelength range reaching sizes as small as less then 500 nm; within the range sufficient to emit light in the blue-white range. Cadmium Telluride Quantum Dots are charged aqueous soluble nano crystals with narrow emission spectra from 490 nm to 740 nm. Cadmium Telluride (CdTe) is also used in solar energy and advanced optical applications.
Cadmium is a Block D, Group 12, Period 5 element. The electronic configuration is [Kr] 4d10 5s2. In its elemental form cadmium's CAS number is 7440-43-9. The cadmium atom has a radius of 148.9.pm and it's Van der Waals radius is 158.pm. Cadmium is a component of some of the lowest melting alloys; it is used in bearing alloys with low coefficients of friction and great resistance to fatigue. Cadmium is used extensively in electroplating, which accounts for about 60% of its use. Tellurium is a Block P, Group 16, Period 5 element. The electronic configuration is [Kr] 4d10 5s2 5p4. In its elemental form tellurium's CAS number is 13494-80-9. The tellurium atom has a radius of 143.2.pm and it's Van der Waals radius is 206.pm. Tellurium is a p-type semiconductor, and shows greater conductivity in certain directions, depending on alignment of the atoms. It is grown in crystalline form with other elements such as indium telluride. Its conductivity increases slightly with exposure to light which makes many tellurides candidates for solar energy applications. . Tellurium improves the machinability of copper and stainless steel, and its addition to lead decreases the corrosive action of sulfuric acid on lead and improves its strength and hardness. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control. Tellurium is used in ceramics. American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis.
