Cadmium Sulfide (CdS)
CRM material co.,limited offer Cadmium
sulfide. Cadmium sulfide (CdS) is an hexagonal, yellowish
crystal with specific gravity of 4.7 and Mohs hardness of
3.8. Synthetic cadmium pigments based on cadmium sulfide
are valued for their good thermal stability in many polymers,
for example in engineering plastics. By adding selenium in
its formula its possible to obtain colors ranging from a
greenish yellow to red violet pigment. The weather resistance
for this pigment is 8 in full tone, which means that it is
a good pigment for UV.
Cadmium sulfide is a direct bandgap semiconductor with a
bandgap of 2.42 eV. It has useful properties for optoelectronics,
being used in both photosensitive and photovoltaic devices.
One simple use is as a photoresistor whose electrical resistance
changes with incident light levels.
Mixed with zinc sulfide, cadmium sulfide acts as a phosphor
with long afterglow.
Thin films of CdS are required in components such as a photoresistor and solar cells.
CdS is known as Cadmium yellow(CI pigment yellow 37 By adding varying amounts of selenium as selenide it is possible to obtain a range of colors for example CI pigment orange 20 and CI pigment red 108.
Synthetic cadmium pigments based on cadmium sulfide are valued for their good thermal stability, light and weather fastness, chemical resistance and high opacity.The general commercial availability of cadmium sulfide from the 1840s lead to its adoption by artists notably Van Gogh, Monet(in his London series and other works) and Matisse ( Bathers by a river 1916-1919) the presence of cadmium in paints has been used to detect forgeries in paintings alleged to have been produced prior to the 19th century.CdS is used as pigment in plastics .
Cadmium sulfide is produced by sulfate reducing bacteria. This ability is being investigated as a means of producing nano- crystalline CdS.
