    Abstract

    The dielectric relaxation dynamics of a dual-frequency liquid crystal-dye composite were studied and the effect of the photoinduced isomerization of the azo dye on the dielectric spectrum of the cell under illumination by an argon-ion laser operating at wavelength of 514.5 nm and irradiance of 550 mW cm(-2) It was found that the illumination process has a profound influence on the dielectric spectrum of the dyedoped dual-frequency liquid crystal in the low-frequency range (C) 2010 Elsevier Ltd All rights reserved.
