چکیده انگلیسی
The third-order nonlinear optical properties, molecular structure and mass attenuation coefficients of nano colloidal silver were studied before and after γ-ray irradiation. Prepared Ag NPs exhibit strong third-order nonlinear optical responses, which have been performed with a Z-scan technique using continues wave (CW) He: Ne laser emitting 632.8â¯nm. Comparing nonlinear results show that the magnitude of nonlinearity enhanced by increasing the dose of γ -ray irradiation. Raman signals of the obtained Ag NPs are significantly enhanced after the γ-irradiation process. Also, the experimental results using gamma spectroscopy method have shown that the mass attenuation coefficients of Ag NPs decrease after gamma irradiation. Briefly, results demonstrated that γ-ray irradiation is an effective method for tailoring the properties of Ag NPs.
