American Elements is a manufacturer and supplier specializing in producing Cadmium Telluride (CdTe) quantum dots with spectra emission ranges from 510 nanometers (nm) to 780 nanometers (nm) wavelengths. They are charged inorganic particles that are available as a powder or in dispersion. Cadmium Telluride quantum dots are nanoparticles of certain semiconductor crystals with the novel property of having an extremely narrow emission spectrum (Gaussian Distribution) that is directly proportional to the particle's size. The smaller the particle the more its emission is blue shifted and conversely the larger the particle size, the more its emission is red shifted, thus allowing for the emission of the complete light spectra of color from the same material. CdTe Quantum Dots have the potential to turn light emitting diodes (LED) from merely display devises to illumination devices creating the first solid state lighting sources. technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. American Elements manufactures quantum dots from several semiconductor materials, including Cadmium Telluride (CdTe), Cadmium Selenide/Zinc Sulfide (CdSe/ZnS), Lead Selenide (PbSe) and Zinc Cadmium Selenide/Zinc Sulfide (ZnCdSe/ZnS) nanoparticles with well-defined peak emission frequencies.

Cadmium (Cd) atomic and molecular weight, atomic number and elemental symbolCadmium (atomic symbol: Cd, atomic number: 48) is a Block D, Group 12, Period 5 element with an atomic weight of 112.411. Cadmium Bohr ModelThe number of electrons in each of Cadmium's shells is 2, 8, 18, 18, 2 and its electron configuration is [Kr] 4d10 5s2. The cadmium atom has a radius of 151 pm and a Van der Waals radius of 230 pm.Cadmium was discovered and first isolated by Karl Samuel Leberecht Hermann and Friedrich Stromeyer in 1817. In its elemental form, cadmium has a silvery bluish gray metallic appearance. Cadmium makes up about 0.1 ppm of the earth's crust. Elemental CadmiumNo significant deposits of cadmium containing ores are known, however, it is sometimes found in its metallic form. It is a common impurity in zinc ores and is isolated during the production of zinc. Cadmium is a key component in battery production and particular pigments and coatings due to its distinct yellow color. Cadmium oxide is used in phosphors for television picture tubes. The name Cadmium originates from the Latin word 'cadmia' and the Greek word 'kadmeia'.

Tellurium Bohr ModelTellurium (Te) atomic and molecular weight, atomic number and elemental symbolTellurium (atomic symbol: Te, atomic number: 52) is a Block P, Group 16, Period 5 element with an atomic radius of 127.60. The number of electrons in each of tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d10 5s2 5p4. Tellurium was discovered by Franz Muller von Reichenstein in 1782 and first isolated by Martin Heinrich Klaproth in 1798. In its elemental form, tellurium has a silvery lustrous gray appearance.Elemental Tellurium The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Tellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining. The name Tellurium originates from the Greek word Tellus, meaning Earth.
