Circularly Polarized Emission from Colloidal Nanocrystal Quantum Dots Confined in Sculptured Thin Film Based Microcavities
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.
