Many previously developed quantum dots were based on materials that involve cadmium, such as cadmium sulfide (CdS) or selenide (CdSe). Although these quantum dots share the same advantages as written above, they hold a deadly threat against the environment as toxic Cd2+ ions may be released through nanoparticle degradation.
Samsung’s quantum dots, however, are cadmium-free. They’re based on indium (In) instead. After much research and development, Samsung is currently the only company that produces cadmium-free quantum dot displays. Samsung started focusing on quantum dots in 2001, and has since registered over 150 patents on the subject.
