Photorefractive properties in a liquid crystal panel with porphyrin dispersed PVK layers
Orientational photorefractive gratings in nematic liquid crystals (NLCs) on a poly(N-vinyl-carbazole) film dispersed with 5,10,15,20-tetra-phenylporphyrinatozinc across poly(vinyl alcohol) film were observed. The maximum diffraction efficiency of 0.3-0.5% was measured.
