  • Abstract
    We report the simultaneous control of the polarization state and emission bandwidth of colloidal nanocrystal quantum dots by embedding them in chiral reflector-based microcavities. Significant improvements in directionality and color purity have been observed in the polarized light output arising from the enhanced coupling between the NQD-excitons and the confined electromagnetic field.
