Los Alamos Team Unlocks the Potential of Spin-Exchange in Quantum Dots

When it comes to producing excitons, manganese-doped quantum dots with a lead-selenide core and cadmium-selenide shell offer a two-for-one deal, with spin-exchange carrier multiplication converting a single photon into two excitons.

A new approach to developing semiconductor materials at tiny scales could help boost applications that rely on converting light to energy. A Los Alamos-led research team incorporated magnetic dopants into specially engineered colloidal quantum dots — nanoscale-size semiconductor crystals — and was able to achieve effects that may power solar cell technology, photo detectors and applications that depend on light to drive chemical reactions.
