摘　　要：利用等离子体电化学法成功制备出银纳米颗粒,并通过局域表面等离子共振效应对颗粒的生长过程进行实时监测,研究了表面活性剂的浓度、种类和前驱物浓度对银纳米颗粒制备的影响。研究结果表明:增大前驱物或表面活性剂浓度对Ag;还原均有促进作用;与聚乙烯吡络烷酮(PVP)和十六烷基三甲基溴化铵(CTAB)相比较,十二烷基硫酸钠(SDS)作为表面活性剂,在相同时间内,生成的银纳米颗粒数量更多,尺寸和形状分布更均匀。Silver nanoparticles were successfully synthesized by plasma electrochemical method.The localized surface plasmon resonance was used to monitor the growth of nanoparticles in real-time.The effects of surfactant concentration,types,and precursor concentrations on the synthesis of silver nanoparticles were further studied.The experimental results showed that increasing the concentration of precursors or surfactant can promote the reduction of Ag ions.When SDS,PVP or CTAB was used as surfactant separately,the experimental results showed that when SDS was used as the surfactant,the number of silver nanoparticles was more in the same period of time,and the size and shape distribution of the nanoparticles was more uniform.
