Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. $21.49. Therefore the ratio between cationic and anionic radii in zinc blend is 0.39 (74pm/190 pm) .This suggests a tetrahedral ion arrangement and four nearest neighbors from standard crystal structure prediction tables. Molar mass of ZnS = 97.445 g/mol. Zinc Sulfide occurs naturally as "blend," and is prepared directly from the elements and by precipitation of a zinc salt solution with ammonium sulfide. Density tends to decrease as temperature increases. In luminescence: Sulfide-type phosphors, activators, fluxes. Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS can be found. 3).2 As discussed previously, zincblende slowly transforms to wurtzite due to thermodynamic stability. Fig 3. Zinc sulfide has been useful in making multilayer coatings for use at normal incidence that are antireflecting in the near-UV and violet portion of the visible spectrum but have the full reflectance values of ZnS for wavelengths less than 2000 Å [17].Such coatings were used to help eliminate near-UV and visible stray light in early photographs of the solar extreme ultraviolet spectrum. .
