Researchers led by a team from the University of Chicago developed a new method to synthesize large-area ("giant") light-emitting QDs that emit light following an exciton state for over 500 nanoseconds, which is a new record.

The new QDs are based on a structure that allows the electrons to focus on holes within a core or shell heterostructure. This is performed by tuning the charge electron to the kinetic energy of a parabolic potential energy surface.
