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 ...

Scientists have found one possible way to induce quantum dots to emit photons faster and more consistently, without their characteristic blinking. The advance could make quantum dots more sensitive as ...

MIT chemists have come up with a way to control the unwanted blinking of quantum dots. (Courtesy: Jiaojian Shi, Weiwei Sun, and Hendrik Utzat, Keith Nelson and Moungi Bawendi, et al.) Quantum dots ...

Quantum dots can be made to emit single photons more efficiently and reliably by using a new method to suppress quantum dot "blinking". A US research team has found a way to reduce quantum dot (QD) ...

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 ...

(Nanowerk News) Quantum dots are nanoparticles of semiconductor that can be tuned to glow in a rainbow of colors. Since their discovery in the 1980s, these remarkable nanoparticles have held out ...

In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than ...

(Nanowerk News) Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions. But for some potential uses ...
