Quantum dots: Louis Brus on the discovery that won him the Nobel prize
Imagine a particle so small that it’s the same relative size to a soccer ball as that football is to the planet Earth. That’s the size of a quantum dot – a type of nanocrystal that changes colour depending on its size, and was once thought impossible to actually make. Now, three scientists who helped discover and synthesise these quantum dots have been awarded the 2023 Nobel prize in chemistry.
In this week’s episode we speak to Louis Brus, one of these new Nobel laureates, and an emeritus professor of chemistry at Columbia University in New York, about his work on quantum dots and what winning the accolade means.
