Best known in high-end TVs, quantum dots could also end up in quantum computers
world is full of paradoxes. Is light made up of particles or waves? How can entangled particles seemingly influence each other faster than the speed of light? And if, officially at least, the Nobel committee does not decide on its prizewinners until late morning, why didin Chemistry was unprecedented. Some mistakenly thought it to be a hoax. But in the end, the leaks were correct.
The dot’s tiny size, though, will constrain the wavelength of the light that the electrons can re-emit. And it is the wavelength of light that determines its colour. Smaller nanodots produce high-energy blue light; larger ones produce red. Go above ten nanometres or so—about a thousand times smaller than a red blood cell—and the quantum effects necessary to produce light smear away into nothing.
As appealing as coloured glass may be, it is a difficult medium for scientists to work with. In 1983 a more tractable manufacturing method was discovered. Dr Brus, then at Bell Laboratories in New Jersey, was able to create them as free-floating particles in solution, allowing the phenomenon to be observed in liquids as well as solids.
