Arsenic Sulfide Nanoparticles

Arsenic Sulfide Nanoparticles

Arsenic sulfide nanoparticles is an inorganic compound composed of arsenic (As) and sulfur (S). It is a member of the chalcogenide group of semiconducting materials, which are known for their useful electronic, optical, and thermoelectric properties. When reduced to the nanoscale, arsenic sulfide (As₂S₃) undergoes significant changes in its physical and chemical properties, making (As₂S₃ NPs) highly useful in a variety of applications, particularly in optical, electronic, energy, and environmental technologies.

Applications:

Arsenic sulfide nanoparticles have a wide range of applications across several industries due to their unique electronic, optical, and catalytic properties:
