Nobel Prize in Chemistry awarded to trio of quantum dot researchers

The Royal Swedish Academy of Sciences (KVA) has chosen its 2023 Nobel Prize in Chemistry winners, and they’re all about quantum dots. The three researchers — Alexei I. Ekimov, Louis E. Brus and Moungi G. Bawendi — will share the honors for their contributions to nanotechnology. Although quantum dots had been proposed theoretically earlier in the 20th century, this year’s trio of Nobel winners began verifying them experimentally. The nanoscale semiconductor particles exhibit quantum mechanical properties, glowing in different colors when exposed to light. “Quantum dots have many fascinating and unusual properties. Importantly, they have different colours depending on their size,” wrote Johan Åqvist, Chair of the Nobel Committee for Chemistry, in a press release. The smaller the dot, the bluer its light is; the bigger the dot, the redder its light is. By changing their size, researchers can tune their colors, leading to various scientific advances.
