Nonlinear optical properties of nematic liquid crystal doped with different compositional percentage of synthesis of Fe3O4 nanoparticles

In this research, Fe3O4 nanoparticles were synthesized and analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The synthesized Fe3O4 with different compositional percentage doped in an E7 nematic liquid crystal (NLC). Nonlinearity of pure and doped NLC with Fe3O4 nanoparticles were studied by z-scan technique (close aperture and open aperture z-scan). The experimental results show that the nonlinear optical responses of Fe3O4 nanoparticles doped E7 can be changed by varying the compositional percentage of Fe3O4 nanoparticles. A small compositional percentage of Fe3O4 nanoparticles, 1% W/W, dispersing in a NLC showed improved nonlinearity.
