The photorefractive effect of smectic liquid crystal blends containing small amount of chiral compound was investigated. The photorefractive ferroelectric liquid crystal blends are known to exhibit a large photorefractive effect. They are composed of Smectic-C liquid crystals, photoconductive chiral compounds and a sensitizer. Smectic liquid crystal blends that contains several concentrations of a chiral compound while keeping a constant concentration of a photoconductive moiety were prepared. The effect of the concentration of the chiral dopant on the photorefractive properties of the liquid crystal blend was investigated.
