Nonlinear Refractive (NLR) Index of TiO2 NPs in E5CN7 Nematic Liquid Crystal under CW Laser Illumination
Procedia Materials Science
Nematic liquid crystals (NLCs) have proved to be excellent materials for nonlinear optics (NLO) and its applications because of their large nonresonant nonlinearity and their extended spectral transparency. The aim of this paper was to investigate nonlinear refraction index of eutectic mixture of heptylcyanobiphenyl 7CB and pentylcyanobiphenyl 5CB NLCs doped with TiO 2 NPs (were synthesized by sol-gel method). The eutectic melt temperature of 273.45 K and eutectic composition of 0.45 7CB weredoi:10.1016/j.mspro.2015.11.044 fatcat:iulwwbyfdzh3tn6455kjiulrbe
