Herein, electron beam irradiation (EBI) was employed to in situ construct Ag-based micro/nanostructures. The composition of AgX@Ag (X = Cl⁻, Br⁻, etc.) composites and the size/morphology of silver nanoparticles (Ag-NPs) were tuned by adjusting the electron beam current density (EBCD) and the feeding dose of electrons. A hypothesis of gas–solid fluid-bed composed of atomic gas and nanocrystals is suggested to discuss the nanoparticle constructions with EBI. The low/medium EBCD creates a fixed fluid-bed for AgX@Ag-NPs and piled-pore architecture of Ag-NPs (PPA_Ag-NPs), while a high EBCD sets up a stirred fluid-bed for monodispersed Ag-NPs. Hopefully, this strategy would promote nanotechnology.

利用电子束原位制备银基纳米结构†

在本文中，电子束照射（EBI）用于原位构建基于Ag的微/纳米结构。卤化银的组合物@的Ag（X =氯^- ，溴^- ，等）复合材料和银纳米颗粒的尺寸/形态（银纳米颗粒）通过调节所述电子束电流密度（EBCD）和电子的输送剂量调谐。提出了一种由原子气体和纳米晶体组成的气固流化床的假说来讨论EBI的纳米颗粒结构。低/中级EBCD为AgX @ Ag-NPs和Ag-NPs（PPA _Ag-NPs）的堆积孔结构创建了固定的流化床，而高EBCD为单分散的Ag-NPs设置了搅拌的流化床。希望这一战略将促进纳米技术的发展。
