The study of multiexcitons in colloidal quantum dots (CQDs) is a timely topic, as these multiexcitons have practical applications in gain devices, photovoltaic cells and as single photon light sources. However, these excitons decay primarily via nonradiative Auger relaxation at a time scale of 10-100 ps, due to the enhancement of many-body interactions inside dots with a typical diameter of 3-4 nm...
