Abstract: Thanks to their tunability and versatility, colloidal quantum dots (CQDs) have been attracting very much interest for laser technology. Such CQDs made of II-VI semiconductor compound offer the potential to bridge the “green gap” in conventional semiconductor materials. However, in optical pump laser configuration, when the energy of excitation photons is much greater than that of emission photons, multiexciton interaction is enhanced, leading to reduced stimulated emission cross-section, broadened gain bandwidth, and enhanced photoinduced a...
