Electroluminescent (EL) behavior has been evaluated in a cell which contained molecular dispersion of 1,4-bis(N,N-diphenylaminophenyl-1,3,4-oxadiazolyl)benzene (OXD) in a low-molecularweight liquid crystal, 4-octyloxy-4[sup ′]-cyanobiphenyl (8OCB). EL emission was observed above the temperature where the OXD/8OCB mixture showed a liquid-crystalline phase. Furthermore, we fabricated an EL device which consisted of interdigital electrodes coated onto a glass substrate. It was found that the EL emission from the device was highly polarized. © 2000 American Institute of Physics.

    A technique was developed and used to measure the rotatory power of 90° twisted nematic liquid crystals in the visible and infrared spectral regions. Experimental results for two liquid crystal mixtures, BDH-E7 and ZLI-1132, are in very good agreement with theoretical calculations for a wide...

    The optical strain characteristics of a reflective holographic-polymer dispersed liquid crystal are investigated. A spectral blueshift and induced polarization dependence are observed to occur with increasing strain. The spectral dependence on strain is explained by the Poisson contraction of...

    The effect of compensation for the spectral dispersion of light polarization states at the output of a single-domain layer of a chiral liquid crystal (CLC) is experimentally studied. It is shown that such dispersion can be decreased significantly with the aid of phase plates of two types that...

    Macroscopically, a polymer-stabilized blue phase liquid crystal (BPLC) is assumed to be an optically isotropic medium. Our experiment challenges this assumption. Our results indicate that the optical rotatory power (ORP) of some nano-scale double-twist cylinders in a BPLC composite causes the...
