(Nanowerk News) Research by Los Alamos scientists published today in the journal Nature documents significant progress in understanding the phenomenon of quantum-dot blinking ("Two types of ...

Quantum dots promise an astounding range of applications, if scientists can conquer their annoying habit of blinking. Researchers recently ran simulations that offer new insights into the problem.

Quantum dots have many possible applications, but they are limited by their tendency to blink off at random intervals. Chemists have come up with a way to control this unwanted blinking without ...

Quantum dots—tiny, intense, tunable sources of colorful light—are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a ...
