Argonne scientists have unveiled new methods for controlling material properties. The breakthrough enables researchers to ...

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a ...

Argonne researchers have shown that they can use light to temporarily alter the crystal symmetry within lead sulfide quantum dots. This process reduces the off-centering of lead atoms and affects the ...

Associate Professor Jia said the researchers achieved this by fine-tuning the structure of the quantum dots at an atomic ...

Photovoltaic (PV) solutions, which are designed to convert sunlight into electrical energy, are becoming increasingly ...

According to Alem, this phenomenon is called quantum confinement. It occurs when the dots are contained in a ... in specific ratios -- you can fine-tune the band gap to emit light at a specific ...

Quantum dots that are small and non-blinking offer new opportunities for dynamic single-molecule imaging in live cells. Fluorescent dyes and proteins have been invaluable for visualizing the ...

Associate Professor Jia said the researchers achieved this by fine-tuning the structure of the quantum dots at an atomic level, reducing defects that can interfere with light emission. “This approach ...
