Abstract

Electro-optical properties of a hybrid liquid crystal composite are investigated in the presence of laser-induced effects. In the scope of this work, various measurements were performed to analyze the effect of laser pumping on molecular reorientation. Electro-optical parameters are investigated under dark and laser-induced conditions for fullerene-doped and undoped samples. Experimental results show a dependence on laser pumping of the switching voltage for reorientation. Dielectric anisotropy is also studied for the mentioned conditions and its dependency is quantatively estimated by capacitive measurements. © 2005 Elsevier B.V. All rights reserved.
