Gold colloids coated with a self-assembled monolayer of an alkanethiol were introduced into a polyethylene matrix by means of solution-casting techniques. We oriented the resulting nanocomposites by uniaxial drawing in the solid state. The absorption spectra of the drawn nanocomposites in the visible wavelength region were found to depend strongly on the(More)
Pixelated, multicolor polarizing filters--of potential use in full-color displays--were produced by what we believe to be a novel method, i.e., masked evaporation of silver and gold onto glass substrates partially covered with separated sub-micrometer-wide strips of oriented poly(tetrafluoroethylene) (PTFE), prepared by friction deposition. The evaporated(More)
