Nanoscale noble metal particles have great potential as optical-limiting materials, whereas the size effect of silver nanoparticles on the optical limiting has been seldom reported before now. Silver nanoparticles with different sizes are synthesized by a seed growth method, and their optical-limiting properties to nanosecond laser at 532 nm are investigated. The results showed that, under the involved conditions, the silver nanoparticles with relatively small particle size behave better for optical limiting, and the nonlinear absorption accounts for the optical-limiting behavior.

不同尺寸银纳米粒子的制备及其限光性能

纳米级贵金属颗粒作为限光材料具有很大的潜力,而银纳米颗粒对限光材料的尺寸效应此前鲜有报道。通过种子生长法合成了不同尺寸的银纳米粒子,并研究了它们对532 nm纳秒激光的光学限制特性。结果表明,在所涉及的条件下,粒径相对较小的银纳米粒子对光限幅表现较好,非线性吸收解释了限光行为。
