Optical gain from polyfluorene keto defects in a liquid crystal mixture

Author affiliations

Abstract

By means of confocal photoluminescence measurements and fs pump–probe spectroscopy, we observe the optical properties of phase separation in a mixture of polyfluorene and Liquid Crystals (LCs). The boundaries of LC-rich micro-domains display a large polarized gain region from keto defects stemming from the single-chain nature of this defect.
