(Nanowerk Spotlight) Quantum dots are being intensively investigated for applications such as light-emitting diodes, solid-state lighting, lasers, solar cells, and fluorescent labels for biological ...

CAMBRIDGE, Mass. -- 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 ...

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 ...

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.

Figure 1: Relationship between charging and blinking in thin-shell and thick-shell CdSe/CdS NQDs. Recently, PL fluctuations were studied in the so-called dot-in-a-rod nanostructures, that have a ...

A team of scientists has synthesized semiconductor nanocrystals, or quantum dots, that are "nonblinking," in that they emit light steadily. Such behavior has long been a goal of scientists working ...

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 ...
