The ‘quantum’ principle that says why atoms are as they are
J. Thomson’s discovery that atoms were not indivisible, but contained smaller, negatively charged entities called electrons — the first subatomic particles to be identified. Then, in 1911 ...

The quantum dots in TVs controversy goes to court, with a Chinese vendor saying it uses cadmium in sets
It said the quantum dot ones in TCL sets contain at lest four micrograms of cadmium per kilogram. Cadmium-selenide (CdSe) is a compound used to make quantum dots. The presence of CdSe in TCL TVs ...

Hisense QLED TVs are just LED TVs, lawsuit claims
such as cadmium selenide or indium phosphide. Being particularly small, their size and shape dictate the color of light they emit when powered, the result of the quantum behavior of their electrons.
