a SAXS pattern of NPL/PNBCB/6OCB composites under field of 5.8 T at 50 °C. b Schematic presentation illustrating CdSe/ZnS NPL dispersion and alignment in a smectic phase PNBCB/6OCB matrix. c, d FM images of a field-aligned NPL/PNBCB/6OCB film as a function of the sample rotation angle, c after alignment under 90° field and (d) realignment under 0° field. The polarizer axis in the emission pathway is always along 0°. e Schematic illustration for the case of (c), showing the origin of the bright and dark state according to the orientation of NPLs relative to the \(\overrightarrow{{{{{{\bf{n}}}}}}}\) axis. f Normalized emission intensity of the aligned NPL/PNBCB/6OCB composite film as a function of the sample rotation angle, determined from the FM images shown in (c) and (d).
