The particles are a few atoms in diameter, can release very bright light and are used in electronics and medical imaging.
By David Keyton, MikeCorder and Christina Larson, Associated PressPermanent Secretary of the Royal Academy of Sciences Hans Ellegren, center, announces the winner of the 2023 Nobel Prize in Chemistry, at the Royal Academy of Sciences, in Stockholm, Wednesday, Oct. 4, 2023. The Nobel Prize in physics has been awarded to scientists Moungi Bawendi, Louis Brus and Alexi Ekimov for discovery and synthesis of quantum dots.
The suspense surrounding the academy’s decision took an unusual turn when Swedish media reported the names of the winners several hours before the prize was announced. The advance notice apparently came from a news release sent out early by mistake.Quantum dots’ electrons have constrained movement, which affects how they absorb and release visible light, allowing for very bright colors.
Judy Giordan, president of the American Chemical Society, said she was thrilled at the selection of the winners. “There was a press release sent out for still unknown reasons. We have been very active this morning to find out exactly what happened,” he said during the news conference where the award was announced. “This is very unfortunate and we deeply regret what happened.”
Bawendi said he was not thinking about the possible applications of his work when he started researching quantum dots.
