a TEM image of CdSe NPLs and molecular structures of 6OCB and PNBCB and their phase transition temperatures. b Stability of NPLs in chloroform with the addition of 6OCB or 12OCB, which is evaluated by the decrease in optical density (OD) of supernatants after gentle centrifugation of the solutions. Photographs of NPL solutions (top) without 6OCB and (bottom) with 13 wt.% 6OCB. c Stability of NPLs in PNBCB/6OCB blend solutions as a function of the 6OCB concentration with constant 3wt.% of PNBCB, and photographs of NPL/PNBCB solutions (top) without 6OCB and (bottom) with 13 wt.% 6OCB in the presence of 3wt.% PNBCB. d Optical microscopy (OM) image of an isotropic NPL/6OCB composite and the small-angle X-ray scattering (SAXS) result. e OM image of an isotropic NPL/PNBCB/6OCB composite and the SAXS data.
