Mork on locking energy-transfer rates in quantum dots


February 4, 2015

MIT chemistry graduate student Jolene Mork examines rates of excitonic-energy transfer. Energy transfer in light-sensitive materials such as quantum dots is of interest for better solar cells, LEDs, and other devices. MIT chemistry graduate student A. Jolene Mork examines how fast energy transfers from one quantum dot to another, a phenomenon known as hopping. Mork is lead author of a Journal of Physical Chemistry paper that analyzed energy transfer in colloidal quantum dots. “It’s not looking at how far can an exciton go within a film; it is how fast does it transfer from one quantum dot to another,” she says. Mork is a fifth-year MIT graduate student in the lab of William A. Tisdale, the Charles and Hilda Roddey Career Development Professor in Chemical Engineering at MIT. Read on at MIT News.
