摘要

Response properties of photoinduced gratings were studied in planar cells of liquid crystal doped with multiwalled carbon nanotubes. The grating formation time deduced from beam-coupling measurements was obtained to be ∼30 ms. Absorption spectroscopy implies that the permanent gratings are associated with periodically distributed carbonaceous material adsorbed on the inner surfaces of the cell windows under prolonged illumination to the 514.5-nm beams, giving rise to the persistent light-induced modulation of the easy axis.
