Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...

(Nanowerk Spotlight) Quantum dots have been receiving extensive attention from researchers because they can be widely used for basic physics study, quantum computing, biological imaging, ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

This method recovered 85% of the original quantum dots, which still performed almost as well as new ones. The recycled dots were then used to make lasers that worked just like the originals. The team ...

Synthesis of semiconductor quantum dots, characterization and their various applications are the frontier research areas at present [1-12]. Different techniques like MBE (Molecular beam epitaxy), RF ...

Depending on their applications, quantum dots need to be tailored in terms of their structure and properties. Chemists have shown that quantum dots obtained by their novel method can be successfully ...

In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricey solvents used in quantum dot ...

Still fluorescent: A sample of the supraparticles recycled in the experiment. (Courtesy: Dillon H Downie, University of Strathclyde) Researchers at the University of Strathclyde, UK, have developed a ...

In what may be one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a ...
