In 1981 Russian solid state physicist Alexey I. Ekimov, working at the Vavilov State Optical Institute in St. Petersburg. discovered the semiconductor nanocrystals known as quantum dots in a glass matrix.

Later, American chemist Louis E. Brus, while working at AT&T Bell Laboratories, discovered quantum dots in colloidal solutions.
