Quantum dots are tiny nanocrystals with extraordinary optical and electrical properties with possible uses in dye production, bioimaging, and solar energy production. Researchers at the University of Illinois at Chicago have developed a way to introduce precisely four copper ions into each and every quantum dot. The introduction of these "guest" ions, called doping, opens up possibilities for fine-tuning the optical properties of the quantum dots and producing spectacular colors. "When...

Surprising breakthrough could bolster quantum photonics, solar cell efficiency Scientists from the U.S. Department of Energy´s National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices. A paper on the new technology, “Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics,”...

Quantum Dots Used To Generate Electricity From Waste Heat

University of Rochester A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. "The system is really a simple one, which exploits certain properties of quantum dots to harvest heat," Professor Andrew Jordan of the University of Rochester said. "Despite this simplicity, the power it could generate is still larger than any other nanoengine that has been considered until now."...
