摘要

研究了以铜、黄铜和18Cr9Ni钢为原料，采用激光烧蚀法制备纳米颗粒的可能性。对于纳米颗粒提取工艺，选择了最有利的脉冲激光参数:激光束功率、激光脉冲数和光束焦点到金属箔的距离。扫描电镜分析证实了纳米球和纳米线几何形状的金属颗粒的存在。

Fabrication of Copper, Brass and 18Cr9Ni Steel Nanoparticles By Laser Ablation Method

The possibilities of nanoparticles fabrication from the selected metals: copper, brass and 18Cr9Ni steel by laser ablation method were investigated. For the nanoparticles extraction process the most favorable pulse laser parameters were selected such as: laser beam power, number of laser pulses and distance of the beam focus from the metal foil. The SEM analysis confirmed the presence of nanospheres and nanowires geometry of metal particles.
