| Outline of Final Research Achievements |
The decay of the photorefractive effect in FLC blends containing terthiophene photoconductive chiral dopants was investigated, focusing on the possibility of photochemical reactions of the components. However, no evidence for photochemical reactions in the blends prepared in this study was observed. In contrast, it is believed that the adsorption of ionic species generated at the photoirradiated spot impedes the photorefractive effect. A bipolar electric field was applied during two-beam coupling trials and it was found that the decay of the gain coefficient was suppressed by the application of this field.
