Working in the laboratory, the team tested two kinds of quantum dots: Cadmium selenide quantum dots, and cadmium-selenide quantum dots with a protective, zinc-sulfide shell. Though the shelled quantum ...

In their experimental set-up, powdered cadmium selenide was heated to hundred of degrees Celsius in a simple horizontal tube furnace under the flow of nitrogen gas, using gold as a catalyst.

Cadmium selenide (CdSe) is a binary, primarily ionic compound with a touch of covalent character. It can take three crystalline forms, but the hexagonal wurtzite structure shown is by far the most ...

Cadmium concentrations in the protozoa predator were approximately five times higher than their bacterial prey. Quantum-dot-treated bacteria were differentially toxic to the protozoa, in that they ...

A solution of cadmium-selenide quantum dots glows orange under ultraviolet light. This luminescence forms the basis for their use in bioimaging. Transmission electron microscopy shows clusters of ...

and coated them with either cadmium sulfide or cadmium selenide - both compounds that can absorb photons. A photon of the right energy hitting the cadmium compounds causes an electron to escape ...

Its CEO Mustafa Ozgen says that the cadmium selenide dots have “significant” advantages over rival technologies in terms of color gamut and energy efficiency that alternatives cannot yet match. QD ...

“We have been focusing on this one type of material, a ternary alloy—mercury cadmium selenide—because we think it could be the ‘perfect’ material to make,” Smith says. “You could ...

Quantum dots made from cadmium and selenium degrade in soil, unleashing toxic cadmium and selenium ions into their surroundings, a new study has found. Quantum dots made from cadmium and selenium ...
