摘要: Abstract The change of refractive index, originated by photoinduced molecular reorientation, brings about a significant diffraction capability in E7 coded nematic liquid crystal system doped 2,3-dicyano-1,4-di[3,4,5-tri(dodecyloxy)phenylcarbonyloxy]benzene (DCDPB) which is called as phthalonitrile derivative. Results grating experiment are reported for the constructed sample. accessible efficiency, η , roughly order 10% under optimum conditions and analysed results propose this novel to be appropriate promising excitation wavelength 632.8 nm He–Ne laser.
