Paper Abstract

We study the enhancement and control of the refractive index of liquid crystals with dispersed gold and silver nanoparticles. The maximum obtainable variation in the real and imaginary parts of the effective refractive index of the solution by reorientation of the liquid crystal molecules is calculated, and the results obtained with gold and silver nanospheres are compared. The effect of size, concentration, and composition of the nano-particulates (solid spheres vs. silver- or gold-coated silica nanoshells) on the refractive index and its wavelength dependence is also considered.
