• min at room temperature. Antispread is a commercially available Fluorocarbon 60 for surface hydrophobization. It forms approximately 40 nm thin layers on the substrate (producer information) and causes no additional nano-structuring on the replica surfaces. A smooth surface, dip-coated with Antispread

• them with a uniform hydrophobic surface coating. For that purpose the surfaces were dipped in Antispread (F2/200 Fluorcarbon 60, Horb-Ahldorf, Germany) for 10 s which forms approximately 40 nm thin layers on the substrate surfaces (product information). After drying for 30 minutes, the hydrophobized

• within these agglomerates is ~2 nm. Conclusion We have prepared highly transparent (>93%) luminescent (QE = 70%) nanocomposites from CdSe/CdS core/shell nanorods in PLMA plates and CTA thin layers. A high QE is observed at low nanorod concentrations (0.008 wt %) in PLMA, corresponding to a concentration
