Abstract
We demonstrated the geometrical effect of nano zinc-oxide (ZnO) on the electro-optical response of a nematic liquid crystal (LC). The experimental results indicated that anisotropic geometrical (nano-rod) ZnO will markedly enhance the photo-refractive effects of host LC, whereas isotropic geometrical (nano-particle) ZnO possess no such effects at all. With the help of photoluminescence spectra and photo-current measurement, we further prove that the geometries of dopants play decisive roles in determining the yield of photo-electron. These results are useful to the nano-technology application of nano-ZnO.
