Which scientists received awards

Nobel Committee on Chemistry recognized scientists’ contribution “For the discovery and synthesis of quantum dots”. This achievement was heralded as a significant moment in the development of nanotechnology.

The basic principle behind quantum dots is emergence quantum phenomenonWhen matter is reduced to the nanoscale. While the behavior of larger elements is determined by the number of electrons they have, the properties of quantum dots are determined by their size.

Johan Eqvist, Chairman of the Nobel Committee on Chemistry, said:

Quantum dots have many interesting and unusual properties. The important thing is that they have different colors depending on their size.

• The concept of size-dependent quantum effects in nanoparticles was a theoretical possibility for physicists, but practical application seemed unlikely due to the difficulties of working with nanoscales.
• In the early 1980s, Oleksiy Yekimov challenged these limitations by demonstrating size-dependent quantum effects in colored glass by using copper chloride nanoparticles to change the color of the glass by quantum effects.
• Louis Brus made history by becoming the first scientist to prove size-dependent quantum effects in particles suspended in a liquid, further confirming the theoretical foundations of quantum dots.
• In 1993, Mungi Bawendi’s revolutionary breakthroughs in chemical production made it possible to obtain near-perfect quantum dots and laid the foundation for their practical use in various fields.

Today, quantum dots play a very important role in illuminating computer monitors, television screens and LED lamps, thanks to QLED technology. They also assist biochemists and doctors in mapping biological tissues.

The potential of quantum dots is far-reaching: Researchers envision their applications in flexible electronics, miniaturized sensors, thinner solar cells, and encrypted quantum communications. As we continue to explore their capabilities, it becomes increasingly clear that these tiny particles have the potential to make a significant contribution to society.

The 2023 Nobel Prize in Chemistry recognizes the outstanding achievements of Bawendi, Brus and Ekimov, who not only advanced our understanding of nanotechnology but also ushered in a new era of technological innovation and discovery.
