Flexible microcavities: directional photoluminescence enhancement

摘要

We have prepared full plastic one-dimensional photonic crystal with a defect layer made of poly(9,9'-dioctylfluorene-co-benzothiadiazole) (F8BT). The optical properties of these flexible microcavities have been investigated and modelled. It is shown that strong directional enhancement of the emission occurs due to light localization in the defect layer.
