Gold nanoparticles (AuNPs) have been prepared for doping liquid crystal (LC) with different concentrations to study linear and nonlinear optical properties utilizing UV spectrum and Z scan technique, respectively. Z scan methods are performed by He-Ne laser at 632.8 Nanometer wavelength. It is observed that the samples can absorb in the UVA range (280-400 nm). Pure LC has high absorbance and the peak of absorbance decreases when the concentration of AuNPS increases due to the AuNPs. The nonlinear optical (NLO) properties of LC were improved by increasing the concentration of AuNPs. The presence of AuNPs changed the behavior of pure LC from two-photon absorption (TPA) to saturable absorption.
