    Fluorescence of the nematic liquid crystal 5CB in nanoporous glasses

    The fluorescence spectra of the nematic liquid crystal n-pentyl-n′-cyanobiphenyl (5CB) in porous glasses with pores from 1 to 44 nm in diameter are investigated. A decrease in the pore diameter leads to suppressi...

    Orientation of pentyl-cyanobiphenyl layers and variations in their luminescence spectra under UV irradiation

    Polarized fluorescence spectra of layers of a nematic liquid crystal (LC) of n-pentyl-n′-cyanobiphenyl (5CB), oriented by two different methods, namely, by rubbing the polyimide-coated substrates holding the LC l...

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

    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 molecul...
