Assessment of Hybrid Organic–Inorganic Antimony Sulfides ...

Antimony sulfide (Sb 2 S 3) is a semiconductor that has been studied since the 19th century owing to its occurrence as the natural mineral stibnite. It has been considered as a candidate for light-harvesting applications due to its favorable material properties. It is reported to be an n-type semiconductor with an optical bandgap of 1.7–1.9 eV, and has a high optical absorption coefficient ...

Antimony trisulfide - Wikipedia

In the extraction of antimony from antimony ores the alkaline sulfide process is employed where Sb 2 S 3 reacts to form thioantimonate(III) salts (also called thioantimonite): 3 Na 2 S + Sb 2 S 3 → 2 Na 3 SbS 3. A number of salts containing different thioantimonate(III) ions can be prepared from Sb 2 S 3 these include: [SbS 3] 3−, [SbS 2] −, [Sb 2 S 5] 4−, [Sb 4 S 9] 6−, [Sb 4 S 7] 2 ...
