| 英文摘要 | Gold nanoparticles protected by a novel pi-conjugated polymer [poly(p-phenylene ethynylene) containing pendent disulfide and bipyridine groups] are synthesized and characterized. the polymer can stabilize the gold nanoparticles effectively. the nonlinear optical properties of the gold nanoparticle colloid solutions in toluene are investigated by using the z-scan technique at a wavelength of 532 nm and pulse width of 4 ns. the gold-nanoparticle colloid solutions show an exceptional nonlinear absorption effect, which simultaneously contains the saturated absorption resulting from third-order nonlinearity and a large reverse-saturated absorption resulting from fifth-order nonlinearity. in addition, asymmetric self-focusing refractive effects are investigated in the colloid solutions. |
