Flying Saucer Quantum Dots: The Secret to Better, Brighter Lasers

Ted Sargent and his team at the University of Toronto have done many things with quantum dots: boost solar cell efficiency, invent infrared imagers, optoelectronics you can apply with a paint brush. Now Sargent and his team have added a new spice to their recipe for colloidal quantum dots that promises to change the struggling prospects of quantum dot-based lasers. If the new approach lives up to its promise, it could lead to brighter, less expensive, and tunable lasers for video projectors and medical imaging among other applications.
