In October 2023, the Royal Swedish Academy of Sciences selected distinguished scientists Moungi G Bawendi, Louis E Brus, and Alexei I Ekimov for the Nobel Prize in Chemistry 2023. They have shared the Nobel Prize for Chemistry 2023 for their groundbreaking discovery and synthesis of quantum dots. They will be awarded on December 10, 2023. The Nobel Prize is considered the most prominent award in six fields i.e. Medicine, Physics, Chemistry, Literature, Peace, and Economic Science. This award was named after Alfred Nobel, who discovered the Dynamite.

Nobel Prize 2023 in Chemistry:

  • The Royal Swedish Academy of Sciences, located in Stockholm, Sweden, has awarded the Nobel Prize in Chemistry 2023 to Moungi G Bawendi, Louis E Brus, and Alexei I Ekimov.

  • They have been awarded for their discovery and development of quantum dots.

Alexei Ekimov
  • In 1980, Alexei Ekimov, a Russian physicist, succeeded in creating size-dependent quantum effects in coloured glass.

  • The colour was from nanoparticles of copper chloride (CuCl).

  • During his work, he also demonstrated that particle size affected the colour of the glass via quantum effects.

Louis Brus
  • Later, the US Professor, Louis Brus proved the size-dependent quantum effects in particles floating freely in a fluid.

  • With this, he became the first scientist in the world to do so.

Moungi Bawendi
  • In 1993, an American Tunisian-French chemist, Moungi Bawendi transformed the chemical production of quantum dots, which results in almost perfect particles.

What is Quantum Dots?

  • Quantum dots are man-made nanoscale crystals, which can transport electrons.

  • Size range: 1 to 100 nanometers

  • Now, Quantum dots now illuminate computer monitors and television screens, which are based on QLED (organic light-emitting diode) technology.

  • They also add light to some LED lamps, and biochemists and doctors use them to map biological tissue.

  • Applications of Quantum Dots:

    • Display Technology (LED, Television screen)

    • Medical Imaging

    • Flexible Electronics

    • Slimmer Solar Cells

    • Encrypted Quantum Communication
