| 摘 要： | 以没食子酸为还原剂和稳定剂,用种子生长法制备出粒径均匀、单分散性和稳定性好、近球形的Ag/Au 核壳纳米粒子.高分辨透射电镜(HRTEM)与 X-射线能量色散光谱仪(EDX)测试表明,在Ag/Au摩尔比为1:1.6时,Au已完全包裹在Ag纳米粒子表面时,平均粒径为25 nm.以此摩尔比制备的Ag/Au核壳纳米粒子为探针...

| Abstract: | Nearly spherical Ag/Au core/shell nanoparticles with good monodispersity and stability were synthesized in aqueous solution by seed growth method using gallic acid as reductant and stabilizer.High resolution transmission electron microscopic(HRTEM) image and energy dispersive X-ray spectrometry(EDX) showed complete coating of gold on the surface of Ag nanoparticles and the presence of Au and Ag in individual nanoparticle with the average size of about 25 nm.The Ag/Au core/shell nanoparticles with Au/Ag mola... |
