Brightness-equalized quantum dots improve biological imaging

Researchers at the University of Illinois at Urbana-Champaign have introduced a new class of light-emitting quantum dots (QDs) with tunable and equalized fluorescence brightness across a broad range of colors. This results ...

'Quantum dot' technology may help light the future

Advances at Oregon State University in manufacturing technology for "quantum dots" may soon lead to a new generation of LED lighting that produces a more user-friendly white light, while using less toxic materials and low-cost ...

Graphene quantum dot LEDs

The first graphene quantum dot light-emitting diodes (GQD-LEDs), fabricated by using high-quantum-yield graphene quantum dots through graphite intercalation compounds, exhibit luminance in excess of 1,000 cd/m2.

Ultra-sensitive sensor detects individual electrons

A Spanish-led team of European researchers at the University of Cambridge has created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the ...

Exotic states materialize with supercomputers

Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers published their results in the journal Science in December 2014, ...
