Quantum dots are tiny nanometer-sized particles that display unique physical properties that allow them to fluoresce across a rainbow of ... such as cadmium selenium or cadmium telluride, ...

Writing in Nature Nanotechnology, Mark Green and co-workers 5 at King's College London now show that earthworms can be used to produce highly luminescent cadmium telluride (CdTe) quantum dots.

As versatile as cadmium telluride quantum dots are, however, they’re not easy to make. It’s especially tedious to fashion them so that they’re not toxic to living cells, since both cadmium ...

To Green, that characteristic behaviour meant only one thing: “It said to me it was cadmium telluride quantum dots,” he says. Observations with an electron microscope showed that he was ...

The materials with the highest luminescence efficiency include quantum dots (QDs), currently used in high-resolution displays, LEDs, ... "We used cadmium telluride [CdTe] ...

Row breaks out over cadmium quantum dot TVs. 07 Oct 2015. ... (RoHS) directive. However, cadmium is also extremely useful for certain optical applications – for example in cadmium telluride solar ...

In biological imaging, quantum dots are used in place of dyes because they can be "tuned" to glow at specific wavelengths. Cadmium telluride dots, for example, glow green when hit with blue light.

Yellow represents a quantum dot (cadmium telluride or indium arsenide, respectively). Blue shows the semiconductor layer securing the quantum dot. view more Credit: Source: Faculty of Physics ...

Hybrid structures containing semiconductor quantum dots and metal nanoparticles could lead to better light-emitting diodes and new nonlinear photonic devices. That is according to researchers in China ...
