Nobel Prize in Chemistry 2023
- The Nobel Prize in Chemistry 2023 was awarded to Moungi G. Bawendi (MIT), Louis E. Brus (Columbia University), and Alexei I. Ekimov (Nanocrystals Technology Inc.).
- The award was given for the discovery and synthesis of quantum dots.
- Quantum dots are integral components of nanotechnology.
- The size of quantum dots determines their properties.
- Quantum dots are used in televisions, LED lamps, and surgical guidance for tumor removal.
- Quantum phenomena in particles arise when matter is shrunk to nano-dimensions.
- The properties of quantum dots are determined by quantum phenomena.
- Johan Åqvist emphasized that quantum dots change colors based on their size.
- Initially, size-dependent quantum effects in nanoparticles were considered theoretical.
- In the 1980s, Alexei Ekimov showcased size-dependent quantum effects in colored glass using nanoparticles of copper chloride.
- Louis Brus first proved size-dependent quantum effects in particles present in fluids.
- Moungi Bawendi, in 1993, significantly enhanced the chemical production of quantum dots.
- Quantum dots play a crucial role in QLED technology for computer monitors and TVs.
- They enhance the light quality of certain LED lamps and help in mapping biological tissues.
- The future applications of quantum dots could include flexible electronics, tiny sensors, slimmer solar cells, and encrypted quantum communication.
- The full potential of quantum dots is still being explored.
