稀土镧对真空蒸发沉积银纳米粒子团聚的影响
摘要:
用透射电镜（TEM）和扫描电镜（SEM）研究了稀土镧对真空蒸发沉积银纳米粒子的影响.结果表明,稀土镧对真空蒸发沉积银纳米粒子有明显的细化作用.稀土镧对银纳米粒子的细化作用,是由于稀土镧增强了基底对银原子的吸附能,使镧和银结合形成的复合小银粒子局限于固定位置,进而减少了相互团聚所致.

Effect of Lanthanum on the Combination of Silver Nanoparticles Prepared by
Abstract:
Effect of lanthanum on silver nanoparticles prepared by vacuum deposition has been investigated by transmission electron microscope (TEM) and scanning electron microscope (SEM) .Experimental results show that lanthanum decreases the size of the silver particles.The reason is that,with the effect of lanthanum,the atomic coherent energy of the substrate increases,the combined nanoparticles of lanthanum and silver are confined to fixed positions,thus coalesce is reduced.
