Z-scan determination of two-photon absorption in Ag nano-fluid prepared using y-radiation methods.

In this work the two-photon absorption (TPA) coefficients of Ag nano-fluid was measured using Z-scan technique. The Ag nano-fluid sample was prepared at 4.71×10-3 M concentrations and was radiated at different doses of γ-radiation. The conventional single beam Z-scan method with open aperture techn...
