Abstract

Au nanoparticles have been synthesis by chemical method. Optical properties of Au nanoparticles have been studied by using UVVis, Z-SCAN METHOD and RAMAN SPECTROSCOPY. In addition, the MASS ATTENUATION COEFFICIENTS of the synthesized nanoparticles at different energies were measured by the gamma spectroscopy method. The UV-Vis spectrum of these nanoparticles exhibit an absorption peak at 530 nm region. Nonlinear refraction and nonlinear absorption indexes obtained in order of 10-8 cm2/W −and 10-4 cm2/W with using continue wave Nd: YAG laser (l=532 nm) by use of closed aperture and open aperture z-scan setup, respectively. The performed measurements show that gamma irradiation affects the mass attenuation coefficient and optical properties of Au nanoparticles.
