Recently, PL fluctuations were studied in the so-called dot-in-a-rod nanostructures, that have a similar composition (CdSe/CdS) but a different morphology 19. They were attributed to switching in ...

Quantum dots, or in scientific parlance, nanocrystal semiconductors, don’t amount to a new display type or resolution. Quantum dots are just a new component in an LCD screen. More specifically ...

A quantum dot is a nanocrystal made out of a semicondutor material which is small enough to take advantage of the laws of quantum mechanics. Quantum dots are at the center of a very new and ...

Samsung pioneered QLED technology – an innovative use of Quantum Dot displays – and continues to refine QLED TVs to ...

US researchers have observed optical gain and stimulated emission at room temperature in chemically-synthesized nanocrystal quantum dots. Based on II-VI materials, the development could lead to a new ...

“In a quantum dot sensitized solar cell, the excitation of semiconductor quantum dot or semiconductor nanocrystal is followed by electron injection into TiO 2 nanoparticles. These electrons are ...

Quantum dots are a kind of artificial atom ... These edge atoms disturb the balance between positive and negative charge carriers inside the nanocrystal and can cause the energy released during a ...

The new nanocrystal products retained the desired properties of the parent CdSe nanocrystals, including size, shape and uniformity. "This is the first example of infrared quantum dots that are at ...

Quantum dots represent one of the most significant advancements in semiconductor nanocrystal technology of the past two decades. These microscopic particles, typically measuring between 2-10 ...

Quantum dots, nanocrystal, magic diodes. Whatever you want to call them, these tiny entities are putting the color back into LCD displays. Shine a backlight at them and they re-emit a very pure ...

We used a particular single emitter called a quantum dot, which is a nanocrystal of semiconductors." Thomas said that using nonlinear optics is less reliable — a pair of usable photons isn't ...
