Tetrahedral, icosahedral, and cubic gold nanoparticles have been synthesized in experiment by reducing chloroauric acid with ethylene glycol (EG) in the presence of poly(vinylpyrrolidone) (PVP). The nonlinear properties of the gold nanoparticles have been investigated by using the Open-aperture Z-sc...
