The nonlinear optical properties of nematic liquid crystal films doped with dyes of fullerene C60 are studied. Nematic liquid crystals were doped with azo-dyes, and tested for their optical storage capabilities. An electro-optical holographic storage grating effect is observed in C60-doped nematic liquid crystal films. The effect is attributed to molecular axis reorientation caused by the combination of an applied DC field and an optically induced DC space charge. The observed nonlinear sensitivity of the films is larger than that of other materials studied.
