Changes in optical properties of TDO BAM BCC Langmuir films during a phase transition

Moscow University Physics Bulletin (Impact Factor: 0.25). 02/2011; 66(1):50-53. DOI: 10.3103/S002713491101022X


The isotherms of water molecule adsorption and the spectra of absorption, diffusion reflection, and polarization of reflected
light for hyperfine Langmuir films that were fabricated based on liquid crystals are investigated. Singularities in the reflection
spectra at the temperature of the structural phase transition (∼70°C) are revealed. Some reasonable assumptions on the nature
of the phase transition are made.
