Nobel Chemistry prize awarded for ‘quantum dots’ that bring coloured light to screens

STOCKHOLM: Scientists Moungi Bawendi, Louis Brus and Aleksey Ekimov won the 2023 Nobel Prize in Chemistry for their discovery of tiny clusters of atoms known as quantum dots, widely used today to create colours in flat screens, light emitting diode (LED) lamps and devices that help surgeons see blood vessels in tumours.

The prize-awarding academy said that their findings on quantum dots, which in size ratio have the same relationship to a football, as a football to the earth, had “added colour to nanotechnology” – when matter is used on an atomic or molecular level in manufacturing.
