Micrometer-scale gold nanoplates have been synthesized in high yield through a polyol process.The morphology,crystal structure and linear optical extinction of the gold nanoplates have been characterized.These gold nanoplates are single-crystalline with triangular,truncated triangular and hexagonal shapes,exhibiting strong surface plasmon resonance(SPR)extinction in the visible and near-infrared(NIR)region.The linear optical properties of gold nanoplates are also investigated by theoretical calculations.We further investigate the nonlinear optical properties of the gold nanoplates in solution by Z-scan technique.The nonlinear absorption(NLA)coefficient and nonlinear refraction(NLR)index are measured to be 1.18×10^(2)cm/GW and-1.04×10^(-3)cm^(2)/GW,respectively.
