NIST studies why quantum dots suffer from 'fluorescence intermittency'
Washington DC (SPX) May 26, 2014
Researchers at the National Institute of Standards and Technology (NIST), working in collaboration with the Naval Research Laboratory, have found that a particular species of quantum dots that weren't commonly thought to blink, do. So what? Well, although the blinks are short-on the order of nanoseconds to milliseconds-even brief fluctuations can result in efficiency losses that could cause trouble for using quantum dots to generate photons that move information around inside a quantum computer or ... read more
