The structure of core-shell Cu@silica and Ag@Si nanoparticles obtained in one-step through evaporation of elemental precursors by a high-powered electron beam are investigated. The structure of the core and shell of the particles are investigated in order to elucidate their mechanisms of formation and factors affecting the synthesis. It is proposed that the formation of Cu@silica particles is mainly driven by surface tension differences between Cu and Si while the formation of Ag@Si particles is mainly driven by differences in the vapour concentration of the two components.
研究了通过高能电子束蒸发元素前驱体一步法制备的核壳结构Cu@二氧化硅和Ag@硅纳米颗粒的结构。对颗粒的核和壳结构进行了研究,以阐明其形成机制和影响合成的因素。提出Cu@二氧化硅颗粒的形成主要由Cu和Si之间的表面张力差异驱动,而Ag@硅颗粒的形成主要由两种组分的蒸汽浓度差异驱动。
