Photoluminescence of pentyl-cyanobiphenyl in liquid-crystal and solid-crystal states

Optics and Spectroscopy (Impact Factor: 0.56). 11/2000; 89(6):860-866. DOI: 10.1134/1.1335034

ABSTRACT The stationary and time-resolved photoluminescence spectra of n-pentyl-n′-cyanobiphenyl (5CB) are studied in a mesophase and solid-crystal state. The photoluminescence spectra of 5CB are determined
by the molecular configuration and the intramolecular charge transfer in the excited state. It is shown that in the mesophase
and solid-crystal state, 5CB exhibits along with monomer radiation at least two types of excimer radiation from different
pre-dimer states.

    ABSTRACT: The steady-state and time-resolved fluorescence spectra of n-pentyl-n′-cyanobiphenyl and a related composite material with gold nanoparticles in the liquid crystalline and solid states have been investigated. The introduction of gold nanoparticles into the liquid crystal leads to a noticeable quenching of fluorescence in the emission region of the predimer and excimer states of cyanobiphenyl. In the solid phase, a quenching of free excitons and a short-wavelength shift of fluorescence bands have been observed.

    ABSTRACT: A different effect of (0001) and (000{1}) crystal facets of the cadmium sulfide (CdS) wurtzite structure terminated with Cd and S atoms, respectively, was observed in respect to the properties of the crystal surface and interface with metal or organic semiconductor contacts. In addition to the different surface morphology, a bare CdS single crystal showed different features in photoluminescence from the Cd- and S-terminated surfaces. Different adhesive behavior of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonic acid) (PEDOT:PSS) films in respect to the Cd- and S-terminated facets of the crystal has also been found. Photovoltaic properties of hybrid CdS/PEDOT:PSS heterojunctions have been shown to be sensitive in respect to the crystal facet used. Thin films of aluminum (Al) equally deposited onto the opposite crystal facets revealed much smaller sheet resistance on the sulfur facet than on the cadmium one, which has been assigned to the difference in both chemical interaction with the surface atoms and surface morphology. Current–voltage characteristics of an apparently symmetric Al/CdS/Al structure with Al electrodes deposited onto the opposite crystal facets showed asymmetric behavior depending on the bias direction applied to the Cd or S-terminated facet, with the barrier for electrons at the Al/S-terminated interface, respectively.

    ABSTRACT: We have investigated the fundamental operation characteristics of light-emitting liquid crystals with an emissive layer of fluorescent dye-doped nematic liquid crystal under the condition of applied AC voltage. The electric field dependent current and luminance properties for different frequencies are satisfactorily explained by an equivalent circuit analysis. We confirm that the luminance steeply plunges as the frequency increases. Such a great suppression is explained by accounting for the cut-off properties of the equivalent circuit and for the effect of ions drift mobility.
