Abstract
Liquid crystal composites form an attractive research area in liquid crystal studies. Among these composites, nematic liquid crystal composited E63 is of particular interest. In the present study, E63 coded liquid crystal composites were dispersed with zinc phthalocyanine (Zn-Pc) and fullerene (C-60), and three samples were prepared as E63, E63/Zn-Pc, and E63/Zn-Pc/C-60 in indium tin oxide coated cells via capillary action. Later, current and capacitance measurements of the samples were carried out in darkness and under ultraviolet (UV) illumination (365 nm) of 100 mW/cm(2) power intensity. It was found that both current and capacitance in the samples are affected by UV light and dispersal of Zn-Pc and C-60. Particularly, dispersal of Zn-Pc led to occurrence of photovoltaic properties, which yielded open-circuit voltage of 0.37 V for the E63/Zn-Pc sample. Furthermore, dielectric constant and dielectric anisotropy values were extracted from capacitance values, and UV light was seen to increase the transition frequency of dielectric anisotropy slightly for all samples.
