The Royal Swedish Academy of Sciences announced on the 4th that the 2023 Nobel Prize in Chemistry will be awarded to Monji Bawendi, Louis Bruce, and Alexei Yekimov for their contributions in the discovery and synthesis of quantum dots. Hans Ellegren, Permanent Secretary of the Royal Swedish Academy of Sciences, announced the list of winners and their main achievements at the Royal Academy's conference hall on the same day. He said that the research achievements that won the Chemistry Prize this year have "planted important seeds" for nanotechnology. The Royal Swedish Academy of Sciences stated in a press release on the same day that quantum dots are a type of very small nanoscale particles. People have long known in theory that quantum effects related to size can occur in nanoparticles, but in the past, when it was difficult to manufacture nanoparticles, few believed that relevant theories could be applied in practice. This year's winners invented and improved the technology for manufacturing quantum dots in the 1980s and 1990s. Nowadays, quantum dots "illuminate" computer displays and television screens based on QLED (Quantum Dot Light Emitting Diode) technology, adding subtle differences to the light of some LED (Light Emitting Diode) lamps, and biochemists and doctors are also using them to draw biological tissue maps. The Chairman of the Nobel Committee on Chemistry, John Orquist, stated in the communique that "quantum dots have many fascinating and unusual properties. Importantly, they have different colors based on their size." The communique stated that quantum dots are bringing many benefits to humanity. Researchers believe that in the future, they can be used in fields such as flexible electronic products, micro sensors, thinner solar cells, and encrypted quantum communication. According to reports, Bawendi was born in 1961 in France and is a professor at the Massachusetts Institute of Technology in the United States; Bruce was born in 1943 in the United States and is a professor at Columbia University in the United States; Yekimov was born in the Soviet Union in 1945 and was a former chief scientist at the American Nanocrystalline Technology Company. During a telephone interview on the same day, Bawendi stated that he was surprised and "completely unexpected" by the award, and felt honored for it. The three winners will receive an equal share of 11 million Swedish kronor (approximately $1 million) in the prize money. (New News Agency)
