Quantum Dot TVs: Thanks to Indium Compounds

  • Indium

  • You may have seen quantum dot televisions in stores – you may even own one yourself. If you are a reader of this blog, you should know by now that ITO (indium tin oxide) is used as a transparent conductive oxide in almost all displays. What you may be unaware of is the role that indium plays in quantum dot TVs.

    It all starts with elemental indium, which is combined with acetic acid to form indium acetate. That indium acetate is shipped to our customers to form quantum dots. There are other materials besides indium acetate that can be used to form quantum dots. However, indium-based quantum dots offer an alternative to cadmium and lead-based materials.

    Common binary quantum dot materials include:

    • indium arsenide
    • indium phosphide
    • cadmium selenide
    • cadmium sulfide
    • lead sulfide
    • lead selenide

    Products made with indium compounds are found all around your house and probably in front of you as you are reading this. Many people know very little about this amazing element. Check out this website to learn more about indium.
