摘要: In this Letter we present the spectral and nonlinear optical properties of ZnO–Ag nanocomposites prepared by colloidal chemical synthesis. Obvious enhancement ultraviolet (UV) emission samples is observed strongest UV over three times than that pure ZnO. These show self-defocusing nonlinearity good absorption behaviour which increases with increasing Ag volume fraction. The explained through two photon followed free carrier absorption. a potential nanocomposite material for light development devices relatively small limiting threshold.
