Tin(II) Sulfide (SnS) and Tin(IV) Sulfide (SnS2) are available as a fine powders.
Tin sulfide has a band gap, Eg = 1.30eV. Silver doping increases the conductivity of the p-type semiconductor.
Tin sulfide evaporated thin films are photoconductive over the range near infrared through to the ultraviolet.
Nano-powders of tin sulfide have been demonstrated to emit in the Blue – UV range making it suitable for optical device applications. Lorad staff will work with customers to supply limited quantities of SnS nanopowder.
The above is an XRD trace for bulk synthesized SnS as a thin film evaporation source.
