Abstract
Z-scan method has been utilized at (532nm) and uv-visible and fluorescence spectrophotometer have been utilized to study the spectral characteristics in order to compute the nonlinear optical properties in two cases close, open aperture. The refractive index n2 and absorption coefficient β of various thicknesses (4,6,8,10,12) μm for constant concentration (5×10-2 M) have been determined. The empirical results for open- aperture showed that the film models of fluorescein sodium dye have shown the saturation absorption or the two photon absorption, also in closed-aperture showed positive or negative effect. Likewise for thicknesses quantum efficiency have been calculated
