- Measurements of Nonlinear Optical Properties of PVDF/ZnO Using Z-Scan Technique Haider Mohammed Shanshool Muhammad Yahaya Wan Mahmood Mat Yunus Ibtisam Yahya Abdullah Física, Astronomía y Matemáticas PVDF scan technique ZnO nanocomposite Nonlinear optical properties The nonlinear optical properties of ZnO nanoparticles dispersed in poly (vinylidene fluoride) (PVDF) polymer are investigated. PVDF/ZnO nanocomposites were prepared by mixing different concentrations of ZnO nanoparticles, as the filler, with PVDF, as the polymer matrix, using casting method. Acetone was used as a solvent for the polymer. FTIR spectra of the samples were analyzed thus confirming the formation of α and β phases. The absorbance spectra of the samples were obtained, thereby showing high absorption in the UVregion. The linear absorption coefficientwas calculated. The single-beam Z-scan technique was used to measure the nonlinear refractive index and the nonlinear absorption coefficient of the PVDF/ZnO nanocomposite samples. We observed that the nonlinear refractive index is in the order of 10−13 cm2/W with the negative sign, whereas the nonlinear absorption coefficient is in the order of 10−8 cm/W. 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46442559006 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.5 Vol.45
