A novel type of orientational photorefractive material based on polymer dispersed liquid crystals (PDLCs) doped with fulleren (C60) was presented. The liquid crystals doped with C60 showed photoconductivity and the holographic grating formation mechanism was originated in the space charge field and resulting reorientation of liquid crystal molecules. The Raman-Nath type of gratings in the PDLCs with a dc applied filod were written by the photorefractive-like space charge field and the large refractive index modulation of the order of 10-3 was obtained. In addition, a stable memory effect of the reorientation was obtained for a 40 wt/60 wt (polymer/liquid crystals) sample.
