How to make bright quantum dots even brighter

Quantum dots are a kind of artificial atom: just a few nanometers in size and made of semiconductor materials, they can emit light of a specific color or even single photons, which is important for quantum technologies. The ...

Super scintillators enable X-ray detection at an ultralow level

The introduction of lead-free metal halide powder into a scintillation screen took some tinkering. Once a KAUST team worked out the right technique, they were able to produce an exceptionally efficient, robust and flexible ...

Organic spacers improve LED performance

Light-emitting diodes (LEDs) release energy in the form of light when electrons and "holes" (electron vacancies) recombine in response to an applied voltage. Over the past few years, scientists have turned their attention ...
