Abstract

The spectral dependences of the refractive index of liquid crystal compositions sensitized with different concentrations of tungsten disulfide (WS2) nanotubes are considered in the present study in the visible spectral range. A correlation between the refractive index and the dynamic properties of liquid crystal cells is established. The characteristics of laser-induced breakdown under the influence of a pulsed laser with a wavelength of 1.54 µm are also considered. The concentration of the WS2 nanoparticles doping the liquid crystal mesophase, at which the phase transition to a quasi-smectic state occurs, was determined. This finding significantly enhances the application range of liquid crystal cells in optoelectronic systems.
