英文摘要The dependence of nonlinear optical response properties of bimetallic alloying and core-shell structure spherical nanoparticles was investigated as a function of relative composition. Numerical calculations based on Drude model and quasi-static theory were developed to describe these absorption properties. With the increasing gold content, the absorption peaks of both alloying Au-Ag nanospheres and core-shell structure nanospheres red-shift from 402 to 526 nm in a nonlinear way. Furthermore, the linearity of alloying nanospheres is better than that of core-shell structure model. In core-shell structure nanospheres, the shell composition characters play a more important role to influence the optical properties of the bimetallic nanoparticles. (c) 2005 Elsevier B.V.
