Nobel Chemistry 2023
Russian physicist who first observed quantum-size effects in semiconductor nanocrystals embedded in glass, the discovery underlying quantum dots.
Nobel-winning work
In 1981, working at the Vavilov State Optical Institute, he discovered that semiconductor nanocrystals grown in glass show size-dependent optical absorption — the first observation of quantum confinement in what are now called quantum dots. His discovery, shared with Louis Brus and Moungi Bawendi, launched quantum-dot science and its applications in displays, imaging and photonics.
