Abstract
In the present work, the spectral properties (absorption and fluorescence) for liquid Aurintricarboxylic Acid compound (B) dissolve in dimethy sulfoxide (DMSO) were studied at different concentrations(1×10−4 and 1×10−5)M, nonlinear optical parameters was study by use technique of z-scan represented by the nonlinear refractive index and nonlinear absorption coefficients, several testing were done including, Fourier-transform infrared spectroscopy(FTIR), nuclear magnetic resonance (NMR),results showed the effect of self-focusing in the material at higher intensities, which evaluated n2,the effect of two-photon absorption was studied which evaluated β. In addition, the optical limiting behavior has been studied, the results confirmed the capability of the sample to be used as optical limiter device.
