Rotation of the light polarization plane in Liquid Crystals with sensitizers based on WS-=SUB=-2-=/SUB=- nanotubes

Abstract

The effect of WS2 nanotubes on the rotation of the polarization plane of p-type laser radiation in the nematic liquid-crystal composites based on 4'-pentyl-4-biphenylcarbonitrile (5CB) has been considered. The correlation between the concentration of the injected sensitizer and the phase shift of the optical beam has been demonstrated. The prospects of these materials in display technologies, laser technology and quantum cryptography has been shown. Keywords: liquid crystals, sensitizing, WS2 nanotubes, rotation of the light plane of polarization.
