History
The study of zinc sulfide fluorescent materials has a history of more than 130 years since it was discovered by the French chemist Sidot in 1868. The study of zinc sulfide materials in the 1920s and 1940s Has always received people's attention.
Physical and chemical properties
Physical properties
White or light yellow powder. In H2S gas, it will turn into crystals after burning. The alpha variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700℃; the beta variant is a colorless cubic crystal with a density of 4.102g/cm3, At 1020 ℃ transformed into α type. Exist in sphalerite. Insoluble in water, soluble in acid. See the sunlight dimmed.
Chemical properties
It will be converted to zinc sulfate when placed in moist air for a long time. It is generally derived from the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, Ag is added as an activator in the crystalline ZnS, it can emit different colors of fluorescence after being illuminated. Used as analytical reagents, coatings, paints, white and opaque glass, filling rubber, plastics, and for preparing phosphors.
