Abstract

In this study, Au colloidal nanoparticle is performed by laser ablation method. The linear and nonlinear absorption of the laser dye Rhodamine B dissolved in DI water with and without the presence of Au nanoparticles were investigated. The emission spectra of the samples were studied. Results show the red shift of the fluorescence emission in the case of dye with the presence of Au nanoparticles. The measurement of nonlinear absorption in Au, Au/Rhodamine B and Rhodamine B solutions were carried out using the standard Z-scan technique. Our measurements indicate positive signs for the nonlinear optical absorption coefficients of the samples.
