Is ZnS an acid or base?
It is obvious that ZnS is stable in acidic pH when Eh is below zero. At alkaline pH, however, ZnS is stable at more negative Eh value. The oxidation product of ZnS is zinc sulfate in acidic solution and zinc hydroxide precipitate in alkaline solution.
Is ZnS a solid?
Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. These two polymorphs are wurtzite and zincblende (also known as sphalerite). Wurtzite has a hexagonal structure, while zincblende is cubic….Introduction.

Is ZnS a semiconductor?
Zinc sulfide is one of the most important II-VI compound semiconductors: it has a large (3.6 eV) direct band gap, a sizable exciton binding energy of 39 meV at room temperature1, and it may in principle support both n- and p-doping.

Is ZnS BCC?
In the zinc blend structure the sulphur ions form an fcc structure and the zinc ions occupy half of the tetrahedral sites in this structure to attain charge neutrality. The crystal has a lattice parameter of 0.541 nm.
Is ZnS fluorescent or phosphorescent?
Zinc sulfide is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substance, a phosphorescent material emits absorbed energy at once.
What is ZnS used for?
The most common use of ZnS is as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative applications.
