II-VI Incorporated was co-founded in 1971 by Carl Johnson. The name II-VI Incorporated is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride consisting of cadmium which belongs to group II and tellurium which belongs to group VI.
What is II-VI company?
II-VI Incorporated, a global leader in engineered materials and optoelectronic components, is a vertically integrated manufacturing company that develops innovative products for diversified applications in the industrial, optical communications, military, life sciences, semiconductor equipment, and consumer markets.
What are II-VI materials?
II–VI semiconductors, ME (M = Cd, Zn, Hg; E = S, Se, Te), include materials such as cadmium selenide (CdSe), cadmium sulfide (CdS), cadmium telluride (CdTe), zinc selenide (ZnSe), zinc sulfide (ZnS), and zinc telluride (ZnTe). II–VI NCs are well known as QDs with size-tunable absorption and emission.II–VI semiconductors, ME (M = Cd, Zn, Hg; E = S, Se, Te), include materials such as cadmium selenide (CdSe), cadmium sulfide (CdS), cadmium telluride (CdTe), zinc selenide (ZnSe), zinc sulfide (ZnS), and zinc telluride (ZnTe).

What does II-VI stand for?
The Roman numerals “II-VI” refers to group II and group VI of the Periodic Table of Elements. By chemically combining elements from these groups, II-VI produced the infrared optical crystalline compounds: Cadmium Telluride (CdTe), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS) and Zinc Sulfide MultiSpectral (ZnS MS).
What does II-VI make?
II-VI Incorporated (II-VI) develops, refines, manufactures and markets high-technology materials and derivative precision components and products for precision use in industrial, military, telecommunications, photovoltaic, medical and aerospace applications.
What is a II-VI material?
II-VI semiconductor compounds are compounds composed of a metal from either group 2 or 12 of the periodic table (the alkaline earth metals and group 12 elements, formerly called groups IIA and IIB) and a nonmetal from group 16 (the chalcogens, formerly called group VI).
