Silver Sulfide

Ag2S (2)

Silver Sulfide Ag2S, grey black solid, CAS Number: 21548-73-2, MW 247.8, density 6.82-7.23g/cm3, melting point 825℃, insoluble in water but soluble in sulfuric acid and nitric acid. Silver sulfide Ag2S is one of the most requisite semiconducting sulfides, which has three basic polymorphic modifications of α-Ag2S phase (acanthite), β-Ag2S phase (argentite) and cubic γ-Ag2S phase. In normal conditions, bulk coarse-crystalline silver sulfide with α-Ag2S acanthite-type structure is a direct semiconductor with wide band gap of 0.9 eV, low charge-carrier mobility and good conductivity. Good chemical stability, ultra-low solubility, the presence of phase transition between a semiconducting acanthite and superionic argentite, which can be induced by external electric field without crystal heating, and unique optical and conductive characteristics of different phases of silver sulfide make it an excellent substance for preparation of nanostructured films and heteronanostructures with improved properties for possible application in optoelectronics, biosensing, in photochemical cells, infrared detectors, resistance-switches and in nonvolatile memory devices, an ideal semiconducting material for preparing low-toxicity quantum dots, photocatalysts in various redox-processes and for producing nanocomposite photocatalysts.
