Scientists Moungi Bawendi, Louis Brus and Alexei Ekimov gained the 2023 Nobel Prize in Chemistry for “the discovery and synthesis of quantum dots”, The Royal Swedish Academy, introduced on a social media put up.  According to the assertion launched by the award-giving physique, the rewards got as these scientists had been concerned within the discovery and growth of quantum dots. 

These nanoparticles are “very tiny” that their dimension determines their properties. These smallest parts of nanotechnology now unfold their gentle from televisions and LED lamps, and also can information surgeons after they take away tumour tissue, amongst many different issues.

Why Moungi Bawendi, Louis Brus, and Alexei Ekimov are chosen for the distinguished award?

The award-giving physique underscores that everybody who research chemistry learns that a component’s properties are ruled by what number of electrons it has. However, when matter shrinks to nano-dimensions quantum phenomena come up; these are ruled by the dimensions of the matter. The Nobel Laureates in Chemistry 2023 have succeeded in producing particles so small that their properties are decided by quantum phenomena. The particles, that are referred to as quantum dots, at the moment are of nice significance in nanotechnology.

“Quantum dots have many fascinating and unusual properties. Importantly, they have different colours depending on their size,” says Johan Åqvist, Chair of the Nobel Committee for Chemistry.

“Quantum dots have many desirable and strange properties. Importantly, they’ve totally different colors relying on their dimension,” says Johan Aqvist, Chair of the Nobel Committee for Chemistry.


Physicists had lengthy recognized that in idea, size-dependent quantum results may come up in nanoparticles, however at the moment it was nearly not possible to sculpt in nano dimensions. Therefore, few individuals believed that this data can be put to sensible use.

However, within the early Eighties, Alexei Ekimov succeeded in creating size-dependent quantum results in colored glass. The color got here from nanoparticles of copper chloride and Ekimov demonstrated that the particle dimension affected the color of the glass by way of quantum results.

A couple of years later, Louis Brus was the primary scientist on the earth to show size-dependent quantum results in particles floating freely in a fluid.

In 1993, Moungi Bawendi revolutionised the chemical manufacturing of quantum dots, leading to nearly excellent particles. This prime quality was vital for them to be utilised in purposes.

Quantum dots now illuminate laptop displays and tv screens based mostly on QLED know-how. They additionally add nuance to the sunshine of some LED lamps, and biochemists and docs use them to map organic tissue.

Quantum dots are thus bringing the best profit to humankind. Researchers imagine that sooner or later they might contribute to versatile electronics, tiny sensors, thinner photo voltaic cells and encrypted quantum communication – so now we have simply began exploring the potential of those tiny particles.
