title: Controlling the influence of Auger recombination on emission from colloidal quantum dots by photonic crystal.
abstract: By investigating the time-resolved spectra of colloidal quantum dots (QDs) on silicon nitride (SiN) photonic crystals (PhCs), it is found that the ratio of charged-exciton (trion) emission and the multiexciton emission to the total emission can be controlled by two-dimensional PhCs. Even by conservative estimates, the ratios of trion to total emission from QDs on PCs reaches 10%, which is much larger than that of the dark state seen in the blinking phenomenon of single QDs. Therefore Auger recombination could be controlled by SiN PhCs.
